Interactions
Activity 1
Discuss with your class or group
how these living organisms
interact with their
environment.
Did your discussion include some of these ideas?
The bird feeds on worms, insects, and
plants in the environment. In this way it
helps control those populations. It can
be a food source for larger animals like
the cat. Sometimes it may help carry
seeds from plants to other areas.
The worm receives nutrients from living
and decaying plants. It is a food source
like the bird. Most of the time it makes
its home underground. Worms work like
plows, loosening the soil, and leaving
nutrients which help plants to grow.
The cat is a predator, an animal that
captures and eats other animals. In this
environment it may eat the bird. A cat
sometimes eats plants to clear out its
digestive system. It can use plants to
hide from its prey.
The butterfly uses the plants in the
environment. It sucks nectar from
flowers and uses plant leaves to lay eggs
on. It helps pollinate flowers. It is a
food source for animals like the bird. It
also adds beauty for the environment.
Plants directly provide food for
the insect and worm in this
environment. They provide
shelter and protection for all the
animals in this community. The
sun, air, soil, and water provide
food and help plants grow.
You might write some of these ideas in
your journal to help you with the next
activity.
