Apparently richer in composition. Indicate what measures can be used to protect animals. What group of animals does the newt belong to?
1) Remember from botany and zoology courses how plants and animals are adapted to their environment.
Animals adapt to their environment with the help of special covers, wool and feathers, camouflage coloring, the presence of defensive needles and claws, and shells. Biological rhythms and seasonal migrations are also adaptations. Plants form specific forms, various modifications of leaves, stems, roots. Leaf fall is an adaptation to the cold season.
2) What primarily influences the placement of plants and animals?
The distribution of plants and animals is primarily influenced by climate.
Questions in a paragraph
*Think about which continents and countries the plant and animal world our country.
The flora and fauna of our country are very diverse. It is similar to the animal world of the mainland North America(Canada, USA). Also, the flora and fauna of Russia are similar to the flora and fauna of neighboring countries.
*Think about how to explain the small growth of plants in the tundra and the tendency of most plants to spread across the Earth. What tree species form the northern border of the forest in Russia and why?
The low growth of plants is explained by harsh climatic conditions and insufficient nutrition and waterlogging. In these conditions, mosses and lichens grow more often. The trees have dwarf forms. The flat territory and the absence of forests cause increased wind speed, so most plants creep along the ground.
The northern border of forests in Russia is formed by cold-resistant conifers - pines and larches.

- Remember from botany and zoology courses how plants and animals are adapted to their environment.
- What primarily influences the placement of plants and animals?
The flora and fauna are often called “wildlife,” thereby emphasizing the role of these components in the biosphere. Exactly Live nature First of all, it personifies for us the beauty of the landscape. Love for living nature enriches our lives, inspires artists, poets, composers, and cultivates humane feelings in people. Caring “for our little brothers” is an indicator of a person’s morality.
It is generally accepted that the most important thing in living nature is vegetation. Even the names speak about it natural areas- taiga, steppes, etc. But the animal world is richer in species composition. In our country there are up to 130 thousand species of animals (of which up to 90 thousand are insects), and higher plants only about 18 thousand. It is interesting that among the representatives flora species predominate herbaceous plants- there are many thousands of them, while there are just over 500 species of trees.
Among representatives of the animal world, insects hold the championship. There are significantly fewer vertebrates, especially terrestrial ones, in the fauna of Russia. Fish are numerous, there are more than 1450 species.
There are very few amphibians and reptiles - only 160 species. The diversity of birds is expressed (including all those that occur during seasonal migrations) by a figure of about 710. Of the mammals, about 350 species live in our country.
The composition and abundance of living organisms is greatly influenced by human activities. As a result, some species have sharply reduced their numbers, and some have even been completely exterminated.
At the same time, there are species artificially introduced into our flora and fauna, for example, the American muskrat, raccoon, mink, etc., and among the plants are the tea bush and bamboo.
The flora and fauna of our country are very diverse. The appearance and composition of the flora and fauna of our country, as well as the entire planet, is determined by two main factors: physical and geographical differences between regions - different regimes of light, temperature and humidity, the nature of the soil, relief features - and geological history territories.
The change in the face of the Earth during geological evolution, its surface and climate, the appearance and disappearance of continental connections were the reason that the processes of speciation proceeded differently in different regions. In the distribution of representatives of certain species of plants and animals, patterns can be traced that are primarily due to latitudinal zonality and altitudinal zonation.
Think about which continents and countries the flora and fauna of our country are similar to.
But all these differences are explained not only modern conditions. Both plants and animals carry in their appearance and distribution features inherited from the distant past. From Central Asia Desert-steppe groups of plants and animals came to us. From Alaska to Far East North American conifers penetrated. The specific features of our Far Eastern flora are combined with the originality of the Manchu-Chinese fauna.
The flora and fauna of Russia were greatly influenced by the Quaternary glaciation.
Main types of vegetation in Russia include vegetation of arctic deserts, tundras, forests, steppes, and deserts.
The vegetation of Arctic deserts does not form a continuous cover. Individual patches of lichens and individual plant stems are replaced by bare areas.
The harsh climatic conditions of the tundra ( low temperatures, large swampy areas, permafrost, strong winds) determine the characteristics of the tundra vegetation cover. Mosses, lichens, and low-growing shrubs predominate here; The absence of forest is also characteristic. Typical representatives of tundra vegetation are moss lichen (“reindeer moss”), green mosses, lingonberries, polar poppies, dwarf birch, and polar willow.
Think about how to explain the small growth of plants in the tundra and their tendency to spread along the ground. What species form the northern border of the forest in Russia and why?
Rice. 60. Typical representatives of woody vegetation of Russia
In the temperate zone, forest vegetation of Russia is widespread, represented by dark coniferous forests from spruce and fir in the north, taiga cedar-larch forests in Siberia, mixed forests from spruce, pine, aspen, birch, etc. middle lane and deciduous forests in the southern regions of this zone.
Using the map (Fig. 60), identify typical representatives of the flora of the forest zone of Russia. Remember from your botany course how taiga plants are adapted to severe frosts.
The steppe zone in its virgin form, unaffected by human agricultural activity, is a sea of grass vegetation. The most common in the steppe are feather grass, fescue, tonkonog, and a host of other flowering plants. Since the steppes are located in an area with insufficient moisture, representatives of herbaceous vegetation tolerate the lack of moisture in the soil well.
In semi-deserts and deserts temperate zone conditions are less favorable for the existence of plants and animals than in the steppe, therefore, as in the Arctic deserts, a continuous cover of vegetation does not form here. Desert vegetation is well adapted to drought: the leaves of many plants have turned into thorns, evaporating a minimum of moisture, the roots are branched and very long. Various types of wormwood and solyanka predominate.
Diversity of the animal world of Russia. The fauna of the Arctic deserts is mainly associated with the sea. Walruses, seals, polar bear, many bird colonies. In the tundra, the number of terrestrial animals increases slightly, although a small number of their species are represented here: lemming, mountain hare, wolf, arctic fox, white partridge, polar owl, reindeer. Huge flocks of migratory birds fly to the tundra in the summer. Waterfowl are especially numerous: geese, ducks, swans.
In the taiga, predators include the bear, wolf, and lynx; from ungulates - elk, wild boar; among rodents the squirrel and chipmunk predominate; Fur-bearing species include marten and sable. IN deciduous forests the number of ungulates increases: deer, roe deer, moose. Birds are more diverse than in the taiga: blackbirds, black grouse, etc.
Rice. 61. Typical representatives of the animal world of Russia
In the steppe the number of birds increases even more. There are many birds nesting on the ground. Some of them feed on plants (quail), others on plants and insects (bustard, little bustard, lark), and others are predators that eat insects and small rodents (steppe kestrel, steppe eagle). There are many rodents in the steppe - gophers, hamsters, voles. By storing large reserves of grain in their burrows for the winter, they cause significant damage to agriculture.
Of the large animals in the steppe, there are ungulates - saigas, which escape from enemies with the help of fast legs.
The fauna of deserts is dominated by reptiles (lizards, snakes), fast-moving ungulates (galled gazelles, saigas, kulans), and rodents (jerboas). Common birds include larks, pipits, desert sparrows, and bustards.
Rice. 62. Game animals of Russia
Plants and animals are perfectly adapted to their habitats. For example, in our forests birch and spruce coexist. Birches promote the growth of shade-loving young spruce trees under their canopy, and then the grown spruce trees are left without light by the birches that helped them grow... Trees in forests, grasses in the steppes, dwarf trees and crooked forests in the tundra - all these are examples of the ideal adaptation of plants to their habitat.
Vary according to appearance and adaptation to the same conditions of animals - flying, running, climbing, swimming.
Birch
The white-trunked tender birch tree has long symbolized Russian nature, Russia. The image of the Russian birch has been sung by many wonderful poets and artists.
Birch trees reach a height of 10-25 m (maximum 45), trunk diameter - 25-120 cm (maximum up to 150).
The bark of birch trees (birch bark) is white in many species. This is the only breed in the world with snow-white bark. The lifespan of a birch is from 40 to 120 years. Flowering from 8-15 years, in plantings - from 20-30 years, abundant and almost annual.
Birch is photophilous and grows successfully in various climatic conditions, frost-resistant, tolerates permafrost, drought-resistant, undemanding to soil fertility and moisture, therefore it is found on rocky, poor sandy soils, and peat bogs. The birch goes far to the north and south, rising high into the mountains. It is one of the first to settle in pine-spruce clearings. In the spring, the birch tree is one of the first to awaken in the forest: there is still snow, and there are already thawed patches near it, orange earrings are swollen on the tree... And in the fall, the birch tree is among the first to rush to put on a beautiful golden headdress...
Brown bear
The brown bear is a mammal of the bear family of the carnivorous order. This is a large animal: body length up to 2.5 m, height at withers up to 135 cm, weight up to 450 kg. Most large bears found in our country in Kamchatka and Sakhalin. Limbs with severely blunted claws. The fur is thick and long. The coloring is monochromatic. The bear lives in various forests, preferring taiga forests, especially spruce forests. Prevails in nutrition plant food: pine nuts, hazel, beech nuts, acorns, all kinds of berries, wild fruits, green parts of plants; Bears also feast on fish and insects. Sometimes the bear attacks wild ungulates and livestock. Causes damage to people by visiting oats, corn, orchards, and apiaries.
For the winter it hides in a den and flows into hibernation. In January - February, cubs appear in the mother bear's den, usually two or three.
The most numerous bears are in Kamchatka, Primorye, Yakutia, in the mountains of Siberia, and in the north-west of the European part of Russia. The bear has become a symbol of the animal world of Russia. For a long time, the figure of a bear has been present in various coats of arms. Most a shining example This can be illustrated by the coat of arms of the city of Yaroslavl.
