All About Food Chains book



 Photo: Nick Hobgood,

As you know, all living things have to eat food. Whether you are a clown
fish or a tiger, food is a necessity! Many different types of animals share
habitats and live in communities together. Many times, one type of animal

will be a source of food for another type of animal in a community.

Within a food chain, some living things are producers and some are
consumers. Plants are producers, as they make their own food (using
sunlight, soil, and other elements). Animals are consumers because they

have to eat other animals and plants.

There are four different types of consumers in the animal kingdom. A
carnivore is an animal that only eats other animals. An herbivore is an
animal that only eats plants. An omnivore is an animal that eats both plants

and animals. A scavenger is an animal that eats dead animals.


The diagram to the left is an
example of two food chains. A food
chain shows the order that animals

eat each other in a community. In
the image to the left, you can see

what animal or plant is food for
another animal in its community. For

instance, the food chain with the
eagle shows how a leaf is food for a
grasshopper, which then becomes

food for a hungry mouse. The
mouse is food for a snake, which is
then eaten by an eagle. In this way,
all of these animals are connected.


What happens to a food chain when the number of animals in a community
changes too much? Sea otters can help us understand the answer to this
question. Sea otters are needed members of the ocean community because
they eat sea urchins. In places where there are low numbers of sea otters,
the number of sea urchins increases too much because they are not being
eaten by sea otters. As a result, the sea urchins eat too much of a food called

kelp, which destroys many ocean communities because many ocean
creatures rely on kelp to survive. This proves how sea otters are not only cute

but needed members of their communities.
