Food , water, shelter and other things from its environment that it needs to live, grow, and reproduce.

An environment that provides the things a specific organism needs to live, grow, and reproduce.

Parts of a habitat that are or were once alive.

Nonliving parts of an organism habitat like water, oxygen, space, rocks, light, temperature, and soil.

A group of organisms that can mate with each other and produce offspring.

All the members of one species living in a particular area.

All the different populations that live together in an area

Organisms that lives in a particular area along with the nonliving elements. The study of how organisms interact with each other and with their environment is called ecology.

Shows the amount of energy that moves from one feeding level to another in a food web

Set of chemical reactions plants use to turn light, water, and nutrients into oxygen and energy in the forms of sugar

Takes place among organisms everyday.

Any relationship in which two species live closely together.

A relationship in which one species benefits and the other species is neither helped nor harmed.

Which is a relationship in which both species benefits.

A relationship that involves one organism living with, on, or inside another organism and harming it.

The number of individuals in an area of a specific size

Environmental factor that causes a population to stop growing or to decrease in size.

The largest population that an area can support

Become the source of food for other organisms in an ecosystem.
