Animals like the lion are known as carnivorous (meat-eating) animals. They feed on smaller animals. But many other animals eat grass or plants. They are called herbivorous (plant-eating) animals.
You may be surprised to learn that there are carnivorous plants as well as carnivorous animals. Plants that grow in poor soil need other food. They trap (catch by a trick) small insects (昆虫) and take their bodies as food.
The pitcher plant (猪笼草) is a common carnivorous plant. This plant has a clever trap like a pitcher or jar. It even has a lid to keep out of the rain. The mouth of the pitcher is covered with something sweet like honeydew(蜜露). Insects come to the plant to feed on the honeydew. When they have eaten all that is round the mouth, they go into the pitcher to look for more. There is more honeydew deep in the pitcher and they go down to feed on it. The inner wall of the pitcher is covered with fine hairs. These hairs point downwards so that the insects cannot climb out of the pitcher. They are trapped in it. They die there, and their bodies are taken as food by the plant.

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
