Each of these living
things is connected in
some way. So, if anything
happens to one of them,
the other one will get
a ected. Some e ects are
so small that you may not
see them, and some are
huge that may change
the life of other living
things.
The best examples
to understand this are
food webs. The sun’s
energy helps plants grow.
Animals eat the plants.
Some animals eat other
animals. Animals die and
their bodies feed the soil.
Plants use the soil to
grow, and the cycle goes
on.
