Back 5

1. Made of cells

Energy

Front 9

What are producers?

Back 9

Plants or other organisms that make their own food.

Front 10

What are consumers?

Back 10

Animals that eat producers.

Front 11

What do decomposers do?

Back 11

Break down sugars and other molecules which can be cycled back to producers.

Front 12

Where is all energy eventually returned to?

Back 12

Environment.

Front 13

What does the interconnection of organisms affect?

Back 13

Structure, size, and composition of populations and communities.

Front 14

In ____, who devised what classification system to organize the diversity of nature?

Back 14

1735
Carolus Linnaeus
Binomial nomenclature (every organism has a 2-part name)

Front 15

What is the use of the names we give each organism?

Back 15

To indicate a degree of evolutionary relationship bewtween organisms.
