Prove the connection between plants and predators, build food chains.

There is a connection between plants and predators. Consider the following food chain:

grass – hare – wolf;

As we can see, the wolf does not eat grass. But he needs substances that plants synthesize. The fact is that predators do not have an adapted digestive system for digesting plants. They need an intermediary – a herbivore. Much of these substances are lost as they are used by herbivores. Therefore, there are many more herbivores (first-order consumers) than carnivores (second-order consumers).
