Koala in the ecliptic forests Eastern Australia lives the koala, or marsupial bear. Most of The koala spends time in the crown of trees, eating eucalyptus leaves. He doesn't eat anything other than them. He descends to the ground only to move from one tree to another. Europeans first learned about it in 1880, when the London Zoo bought a live animal. Because of its thick and beautiful fur, an uncontrolled hunt began for the koala. As a result, by the beginning of the twentieth century it was on the verge of extinction. The Australian government passed a law banning hunting and creating a network of nature reserves to protect it.

Emperor Penguin The largest penguin found in Antarctica is the Emperor Penguin. It was discovered by the outstanding Russian navigator, Admiral Farad Bellingshausen during a trip to Antarctica. Huge colonies of emperor penguins are located under the protection of cliffs near the sites open sea. Interestingly, emperor penguins hatch their chicks in the midst of the harsh Antarctic winter. IN severe frosts penguins gather in close groups, preventing the chicks and each other from freezing.

In modern geological epoch There are 6 continents: Eurasia, North America, South America, Africa, Australia and Antarctica. (Fig. 1).

Let's get acquainted with some plants and animals of each continent.

Plants and animals of Eurasia.

This is the most big continent on Earth. Russia is located on it. But today we will meet prominent representatives of other countries, for example, China.

They grow here cultivated plant, known throughout the world, the name of which translated means: “the basis of human nutrition.” This is rice. (Fig. 2). Now they have learned to cultivate this crop in many countries of the world. The peoples of Asia deify this plant, calling it a symbol of the sun and food of the gods. Fields with this plant look quite unusual (Fig. 3). They are completely filled with water.

Rice. 2. Rice plant

Rice. 3. Rice field

Rice is not a plant that lives naturally in water. Residents of Asia discovered that rice growing in a field flooded with water yields 20 times more than in a dry field. Evidence discovered during archaeological excavations in China, they show that rice has been grown there for 8 thousand years. In a flooded field, water insulates the rice seedlings from heat and cold. Water in a flooded field appears to kill all weeds. A flooded rice field does not require artificial fertilizers. It can maintain the level of natural fertilizers for a long time if it gets a little help, for example, burning the remains of sprouts in a dry field and mixing them with soil, scattering animal excretions or food scraps. Raising fish or ducks in a flooded field also fertilizes the soil.

Field processing. The peasant harnesses the oxen to the plow and plows the land. The process of flooding a field involves mixing soil with water and turning it into homogeneous mud. When the soil is mixed, rice grains are planted in special greenhouses. This is done in order to highlight strong shoots and improve conditions for initial growth. Direct planting on the field does not give good results, since grains have difficulty germinating in a flooded field. The soft seedlings are harvested when they reach a height of about 10 cm. Bundles of rice stalks are made and taken to the flooded field for planting. They don't need to be planted in the ground, they are simply thrown into water and they take root on their own. Every kilogram of rice we buy is watered with an average of 4 thousand liters of water. The Chinese have learned great art in regulating the flow of rivers in order to water their rice fields. The water in the canals is in constant movement and does not stagnate. Rice can be grown year after year in the same field without interruption, even for 2 thousand years in a row, which is not typical for other crops.

Animals of China.

One of the animals of China is the giant panda. Lives only here. It is one of the rare, little-studied animals. (Fig. 4).

Rice. 4. Giant Panda

The giant panda was discovered in 1869 and captured only 68 years later. At one time it was even considered extinct. Only in 1937, the first giant panda was caught - a young female, who was named Sulin. But she did not live long in captivity and died a year later. The panda hunters now had more experience. And soon they caught another female, named Mei-Mei.

The word "panda" itself comes from the local name for this animal, which means "bamboo eater." This animal feeds only on thin bamboo shoots. The giant panda, or bamboo bear, is a mammal of the bear family with a peculiar black and white coat color, which has some characteristics of raccoons. The body length of a giant panda is about 1.5 meters. The fur is thick and very beautifully colored.

Animals of Africa.

Africa is home to the tallest animal in the world - the giraffe. Thanks to its incredibly long neck, its height reaches 6 meters. (Fig. 5). This height and very sharp vision allows him to notice moving objects at a distance of about 1 km. It is no coincidence that the giraffe turns out to be the guardian of the animals living in the neighborhood: antelope, zebra, ostrich. A giraffe feeds on tree leaves.

Rice. 5. Giraffe

Africa is the hottest continent on our planet. One of the most famous plants of this continent is the baobab. The baobab tree stores water in a trunk up to 10 m thick. Its soft wood, like a sponge, can accumulate up to 120 tons of water. In dry years, the tree loses a little weight, and after rains it becomes plump again. (Fig. 6). Each baobab flower lives only one night and withers at dawn. Feasting on the pollen and nectar of flowers, bats and lemurs pollinate them. At night, these animals mysteriously rustle the leaves on the tree. No wonder Africans believed that a spirit lives in every baobab flower.

Among the plants of this continent, the growing coniferous trees - sequoias - are especially interesting. These are giant trees: more than 100 m in height and up to 10 meters in diameter. (Fig. 7). They live for several thousand years. And the sequoia cone is the size of a large melon.

Animals of North America.

Among the animals of North America, let's name a small animal that absolutely everyone here knows. He is not hiding from anyone. It's a skunk. (Fig. 8). With wide white stripes on an almost black body, it attracts attention from afar. Few people dare to approach him. When in danger, it emits such a disgusting smell that neither animals nor people can stand it, but quickly run away.

Rice. 8. Striped skunk

Sequoia has excellent wood that is highly valued in carpentry. It is almost not affected by fire. The redwood tree is not only adapted to survive by enduring forest fires, but also needs them. Without them, sequoias would not have survived to this day. Sequoia loves the sun. Its young trees cannot survive in the dense spruce growth at the foot of mature trees. Its seeds have difficulty germinating through a layer of fallen leaves and needles. The fire, without causing much harm to the forest giants, burns out the undergrowth and pine needles lying on the ground.

The tallest tree in the world is the Hyperion sequoia, whose height is 115.61 m.

Nature has endowed these animals with an unusual, but very effective weapon: turning around with their rear, they spray a yellow oily liquid. A dense stream flies 4-5 meters! The main substance in " chemical weapons skunk - ethyl mercaptan. A person can smell it even if he inhales only 0.000000000002 g of it!

Here on the Amazon River you can find the most amazing plant in the world: the water lily Victoria regia. The leaves of this water lily are up to 2 m in diameter. A child can sit on such a sheet. (Fig. 9). The sheet does not sink even after a 9 kg board is placed on it, on which a woman weighing 63 kg stands. It is easy to calculate that the sheet withstood a load of 72 kg.

The world's largest butterfly lives in South America - gray agrippa (Fig. 10).

Its wingspan is almost 30 cm. The largest beetle in the world also lives here: the titanium woodcutter. Its length is 18 cm.

Australia is the smallest and driest continent. The most famous plants of this continent are eucalyptus trees. (Fig. 11). There are also small shrubs.

Rice. 11. Eucalyptus

Rice. 12. Kangaroo

Marsupials are an ancient group of mammals that appeared on Earth more than 60 million years ago. There are about 250 species, of which 180 species live in Australia and its neighboring islands. About 50 species of kangaroos alone, both modern and extinct, are known. (Fig. 12). Australia is the kingdom of marsupial mammals. The marsupial wolf, marsupial mole, marsupial mouse, and marsupial bear are found here. Of course, the marsupial wolf is not in any way related to the wolf living in our area. All marsupials give birth to very weak and underdeveloped young, which are more similar to embryos than to young animals. The largest living marsupial is the gray kangaroo. Its length is 3 meters and its weight is 80 kg. It gives birth to a tiny baby, 3 cm long and weighing only 2 g. However, this helpless creature is able to crawl along the mother’s stomach to the opening of the pouch, find the nipple and attach to it. The baby kangaroo is weak and cannot suckle on its own. Milk is injected into him by his mother through the contraction of a special muscle - the mammary gland constrictor. A baby kangaroo, sensing danger, jumps into its mother's pouch. He does this even as he grows up and becomes an adult. It's a funny sight.

Live in Australia different types kangaroo. From dwarf ones, the size of a hare, to giant ones, three meters tall. These animals carry their young in a pouch on their stomach.

Rice. 14. Penguin

Few living creatures have adapted to the harsh conditions of this continent. Mosses and lichens are found in coastal areas. (Fig. 13). The most famous animal of Antarctica is penguins. (Fig. 14). These birds cannot fly, but they swim and dive very well. They get their food in the sea. Mainly fish.
