10. Animals don’t get there energy directly from the sun, but all plants do. Some animals eat plants, and other animals eat animals that eat plants.

11. The first link in our food chain is called the Producers
The first link in our food chain is called the Producers. Green plants, protists and monerans are called producers, because they make their own food.

12. The second group is the consumers
The second group is the consumers. Consumers eat other living things for energy.

13. The third group is the Decomposers
The third group is the Decomposers. These creatures feed on the wastes of plants and animals or on their remains after they die. They return the nutrients to the soil for plants to use as the cycle begins again.

14. A food chain is a direct link of living creatures where the creature above uses the one below for food.

19. When food chains connect and overlap it is called a food web.
