How animals and plants adapt to their environment two examples each .

Danny the crocodile farts, and the duck Candy Candy who is following Danny stinks and shouts to stop playing with Danny. Giraffe Xiaoli tells everyone that there is no shame in farting, and when a skunk encounters danger, it will also release a very stinky smell to protect itself.

1.Polar bear's protective color.

A marine mammal.

It is also the largest bear species in the world. Polar bear males can reach a meter in length, with an average weight of 400 to 600 kilograms, ** black, usually white in appearance due to transparent hair, but also yellow and other colors, huge and fierce.

2.Frogs hibernate.

Frogs belong to the phylum Chordates.

Amphibians, anceridae, and frog family amphibians, adults without tails, eggs laid in water, fertilized in vitro, hatched into tadpoles, respiration with gills, after mutation, adults mainly use lung respiration, and also use ** breathing.

3.The body of the fish is fusiformal

Fishes are covered with bony scales, breathe with gills, swim through the oscillation of the tail and trunk, and the coordination of fins, and rely on the upper and lower jaws.

Feeding ectothermic aquatic vertebrates, belonging to the vertebrate subphylum of the phylum Chordates.

4.In order to escape predators, zebras are covered with black and white threads.

Zebras are highly social and social animals, and they forage together mainly for grass and even groom each other's fur. Zebras inhabit groups, and even older individuals are not expelled from the group and live alone.

5.In order to adapt to the sands of the desert, camels have evolved soft, wide soles so that they do not sink into the sand

Camels, known as the ships of the desert, have smaller heads and thick, long, curved necks like goose necks. The body is tall and has brown body hair. Extremely able to endure hunger and thirst. Camels can survive without water for 2 weeks and up to a month without food.

1 Cactus leaves degenerate into thorns, reducing water evaporation and adapting to desert environments.

2 Blue whales adapt to the ocean and their feet become fins.

3 Camels adapt to the desert to form humps, and soles of the feet to form calluses.

4 Birds are suitable for flight, and their bodies are streamlined, with their whole body covered with feathers and their forelimbs turned into wings.

5 Locusts have exoskeletons for their adaptation to life on land.

6 The crown of the flag tree is long downwind, which prevents the branches from being broken by the wind.

In the beginning, everyone changed randomly. Those who don't fit in are dead. The rest, naturally, is adaptive.

However, after the sleepy boy brightened, these adaptations continued to change randomly. Those who became more uncomfortable died. The rest is more suitable.

At the same time, the environment is changing, sometimes gradually, sometimes abruptly. Those who don't adapt to the new environment are dead. All that's left is to adapt to the new environment.

Later, in all kinds of random changes, a new way of changing appeared. Instead of outputting a fixed result, it takes the input from the environment and then gives a corresponding output. Most of these changes turned out badly, and they all died.

But in some contexts, there have been several such changes that have been successful. They survived. So we now have two types of change.

It is possible to change the characteristics of the organism itself, as well as the way in which the organism responds to the environment. Finally, intelligent life was born, and with it came true culture. So we can use "learning" to broadly and nurturably change the way we deal with our environment.

So now we have three means of "changing our structure and adapting to the environment". The first is to rely on random mutations to directly change our structure. The second is to rely on fixed physiological mechanisms to respond to the environment and change our structure.

If this physiological mechanism is not good enough, see 1Third, we need to change our structure through learning and culture. If learning and cultural competence are insufficient, see 1 and 2
