Interdependence is when

things depend on each other.

The world shows many

examples of interdependence

where living things can not

survive on their own. Living

things depend on living and

non-living things. For example,

all living things need water

(which is a non-living thing) to

survive.

Life exists everywhere on

Earth. If you travel through the

ocean, you nd living things

there such as sh. You nd birds

in the air and also animals on

land. There are even living things

you can not see like bacteria.
