Bears, giraffes, wolves live on which continent

The spine of mammals: composed of a series of vertebrae, which can be divided into five parts: cervical, thoracic, lumbar, recommendary, and caudal vertebrae. Cervical vertebrae are usually 7 in size, with only a few species having 6 (e.g., manatees) or 8 10 (e.g., three-toed otters), and the vast majority of mammals have 7 cervical vertebrae regardless of neck length (e.g., giraffes and hedgehogs).

The first cervical vertebra is called the atlas vertebrae, and the second cervical vertebra is called the pivotal vertebrae, the atlas is annular, forming a pair of articular surfaces and occipital ankle related joints in front, and the front end of the pivotal vertebral body forms a tooth process that extends into the vertebral foramen of the atlas vertebrae, giving the head flexible turning. The thoracic vertebrae are usually about 13, and each thoracic vertebrae are connected to the ribs, and together with the ribs and sternum, they form the thoracic cage; Mammals such as the sternum segmented, the flying bat, and the burrowing mole under the camp have keel protrusions similar to those of birds. The lumbar vertebrae are 4 7 pieces.

The bones are 3 8, and they are fused into one, and they are related to the girdle; Cetaceans without hind limbs with inconspicuous bones. The number of tail vertebrae varies greatly with the length of the tail, ranging from a few to dozens.

Mammals are basically 7 knots.

Jumping into the water and swimming over, he didn't say that there were crocodiles, giraffes, elephants, and one didn't know.

The giraffe (scientific name: giraffa camelopardalis) is a ruminant cloven-hoofed animal that grows in Africa, and its Latin name means "leopard-print camel". They are the tallest living terrestrial animals in the world.

Standing can reach 6-8 meters from head to toe and weigh about 700 kilograms, with newborn pups being meters tall.

Giraffe males are meters tall and females are meters tall; Males weigh 900-2000 kg, females 700-1300 kg; Neck length average m; Height at birth; Weight at birth 44-70 kg. Both males and females have a pair of small short horns on the top of their heads, with a light brown background and will not be taken off for life. In addition, it has two pairs of horns behind the ears and behind the eyes, but they are not obvious.

Some male giraffes also have a horn on their foreheads. Therefore, they have 6-7 horns. The eyes are large and prominent, located on the top of the head, suitable for distant viewing.

In addition to a pair of large eyes, which are natural "lookout posts" to monitor the enemy, they will constantly turn their ears to look for the source of sounds, and will continue to eat until they are sure that they are safe. The head of a giraffe has a hard horn-like skull. The giraffe has a short coat all over its body, and is dressed in a light yellow background with a coat covered with black-brown spotted reticulation of different shapes and sizes, and the spotted reticulation on the ** is a natural protective color.

The giraffe is an endemic animal in Africa, with a long neck, raised head, and the tallest male giraffe can reach a height of 6 meters, making it the tallest animal on land.

Giraffes usually have a pair of horns that will not be shed for life, and the spotted reticulation on ** is a natural protective color. Giraffes like to live in groups, usually more than ten of them live together, sometimes as many as a large group of dozens. Giraffes are timid and kind creatures that immediately run away whenever they encounter a predator.

It can run at speeds of up to 50 kilometers per hour. When it can't run away, its giant hammer-like hooves are very powerful.

Explain the meaning to you.

Wolves eat giraffes, giraffes will not be less. On the contrary, the population of giraffes will be stronger. Because the wolf knocked out the sick giraffe. The rest are fast runners and strong survival skills.

The wolves were killed, and the giraffes had no natural predators. They will reproduce indiscriminately, causing ecological imbalance, and the end result is less and less food. The giraffes had nothing to eat, so the number of them naturally decreased.

The meaning of the story is that when a population is threatened by an external enemy, although it will be affected and lost, it will also evolve and grow in the loss, and even become stronger, which can be exchanged for the long-term reproduction and existence of the entire population at a very small price, and when the external threat disappears, a population without a sense of crisis will gradually weaken and die out due to lack of competition.

The reason for the biological chain! Every link in the biological chain is indispensable, the wolf here is mainly the role of the consumer, preventing the proliferation of herbivores, and in nature, the carcasses of carnivores after death decompose in the ground, providing the earth with part of the fertilizer needed to grow plants.

The story between the wolf and the deer teaches that there is a close connection between things, and if this connection is broken, the ecological balance is destroyed and will be punished by nature.

The result of natural selection.

Giraffes are huge and difficult to move around in the woods. Also, don't think that the savannah is full of grass. There are also a lot of trees in the savannah. Giraffes are tall and can eat the leaves on tall trees.
