The role of both crawlers in the biosphere

It can maintain the ecological balance and promote the material cycle of the ecosystem, and some amphibians and reptiles will eat pests, protect the growth of crops, and can also convert the organic matter eaten into inorganic matter.

Amphibians and reptiles are mostly in the middle layer of the trophic level of the ecosystem, which is an important link in the process of material circulation and energy flow in the ecosystem. Therefore, its species, quantity and ecological status can often reflect the level of ecosystem biomass and the status of the food chain, which is an important basis for evaluating the status of the ecosystem.

The two reptiles play a role in the whole ecosystem.

What it does: They convert invertebrates and plants that are not directly available to large mammals into nutrients such as animal protein.

The two reptiles play a role in the whole ecosystem. On the one hand, they talk about the conversion of invertebrates and plants into animal protein that cannot be directly used by large mammals.

Amphibians and reptiles are ectotherms.

ectotherms are not ruthless and have cold blood.

Just because of the inside of these animals.

There is no self-regulating mechanism for body temperature.

It can only regulate the emission of body heat by its own behavior.

or absorb heat from the outside environment to raise body temperature.

When the ambient temperature rises, their metabolic rate increases.

As the body temperature rises gradually, it passively leaves the unfavorable environment.

Temperature changes on a global scale, so that they can hide?

As a result, they are subject to increased temperatures and.

The threat posed by climate change is even greater.

It can convert some vertebrates and plants that cannot be directly used by large mammals into nutrients such as animal protein, and at the same time play an important role in controlling pests and rodents.

On the vast ecological map of China, what kind of area is the Longmen Mountain ** belt where Wenchuan is located? Researcher Liu Qing, director of the Ecological Research Center of the Chengdu Institute of Biology of the Chinese Academy of Sciences, gave us a "heavy" explanation - the Longmen Mountains, located in the upper reaches of the Minjiang River, are in the transition zone between the first and second largest topographic ladders in China, and belong to the transition area from the Qinghai-Tibet Plateau to the Sichuan Basin. The maximum elevation difference of this "Southwest Alpine Valley Area" is more than 5,000 meters, including three major ecosystems, from top to bottom, namely meadow ecosystem, forest ecosystem and arid valley ecosystem, which is one of the "key areas" for biodiversity conservation in China.

In short, the dense primeval forests and vast alpine grasslands constitute the ecological barrier of the 'land of abundance', and its health status not only affects the ecological security of the industrial belt in the upper reaches of the Yangtze River, but also relates to the sustainable economic and social development of the entire basin. "Obviously, the original ecological mission of the affected area has gone far beyond people's visual landscape significance.

Two climbs as a consumer, promoting the ecological balance of the material cycle.
