1. The living part of an environment is called its BIOTIC FACTOR. It comprises of plants, animals and microbes in the environment.

2. The collection of abiotic and biotic factors in an environment is referred to as an ECOSYSTEM. The ecosystem is the interaction of the biotic components with the abiotic components of the environment.

3. An ORGANISM is a single living thing that can breed/produce fertile offspring

4. A BIOME consists of an ecosystem with same climate and similar communities.

5. POLULATION in biology refers to individuals of the same species that live in the same area or habitat.

6. The BIOSPHERE refers to the earth with all the ecosystems in it.

7. A COMMUNITY is a group of different interacting populations that live together in an area.

8. ABIOTIC FACTORS are the nonliving part of the environment, consisting of land, soil, water etc

9. The levels of organization in order from 1 to 4 starting with the simplest is as follows:

1) Organism

2) Population

3) Community
