particular animal is usually found in a specific part
of a shore.
Plants and animals in a location interact with one another.
different ecosystems may be found in one location.
and animals are not randomly distributed on our shores. To find
them, it helps to understand where and how they live.
| Habitat: Each living thing

Overlaps occur as one ecosystem gradually changes into adjoining
