This document discusses food chains and the relationships between producers and consumers. It defines key terms like producers, consumers, herbivores, carnivores, and omnivores. Producers are organisms that can make their own food, like plants, while consumers eat other organisms for food. Herbivores eat producers or plants, carnivores eat other consumers or animals, and omnivores eat both producers and consumers. Food chains show the transfer of energy from one organism to another, with producers at the start of the chain and top predators at the end.

8. Food Chains
Food chains show us what is eaten by what.
Look at the food chain below:
grass  rabbit fox
The  shows the direction of energy flow in the chain. We
can imagine that the arrow means ‘eaten by’, so energy is
transferred in the direction of the arrow.
So this food chain says:
Note that food chains always start
with a producer.
Grass is eaten by the rabbit, which is eaten by a hawk.
