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

Animal that are or were alive and that interact with an organism

The nonliving parts of an organism habitat these physical components include water, oxygen, space, rocks light, temperature, and soil

A group of organism that can mate with each other and produce offspring that can also mate and reproduce

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

All of the different populations that live together in an area

The community that lives in a particular are along with the nonliving environment

The study of how organisms interact with each other and with their environment

The number of individuals in an area of a specific size population density can be represented as an equation.

An environmental factor that causes a population to stop growing or to decrease in size, such as a fatal disease infecting organisms, organisms is a limiting factor.

The largest population that an area can support.

An organism that can make its own food

Obtains energy by feeding on other organisms

Breaks down biotic wastes and dead organisms, returning the raw materials to the ecosystem

A series of events in which one organism eats another and obtains energy and nutrients

Many overlapping food chains in an ecosystem

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

Absorbs light ,much like cells in solar panels do

An organism that makes it own food

An organism that has to get food from a source

Includes how an organism obtains its food,the type of food the organism eats and what organisms eats it

When two species share a niche one of their populations might be affected

An interaction in which one organism kills another for food or nutrition

Any relationship in which two animals live closely together

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

A relationship which both species benefits
