heterotroPH because they cannot produce organic substances from inorganic substances but depend directly or indirectly on organic substances produced by producers. Consumers ultimately depend on plants for food (either directly from plants or indirectly from animals that feed on plants). Animals that eat plants directly are called herbivores, also known as primary consumers (such as locusts, rabbits, horses, etc.); Animals that eat plants are carnivores, or secondary consumers, such as hare-eating foxes and antelopehunting cheetahs. Then there are the third-tier consumers, the fourth-tier consumers, and the top carnivore.

Therefore, we need to be full of awe for nature, and we should not destroy it. After the pollution of the natural environment, people will slowly destroy themselves through the food chain. Therefore, we need to protect the environment and should not destroy the ecosystem, which will cause irreparable harm to people. The balance between city and nature should not be lost

Ecological system, referred to as ECO, refers to the unified whole formed by organisms and environment in a certain space in nature. In this unified whole, organisms and environment influence and restrict each other, and are in a relatively stable dynamic equilibrium in a certain period of time. The range of ecosystems can be large or small, interleaving each other. The solar system is an ecosystem, and the sun is like an engine, providing energy to the solar system continuously.
The Food chain is also called the nutrition chain. In order to maintain their own life activities, all kinds of organisms in the ecosystem must take other organisms as food
