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

The parts of a habitat that are or weee once alive and that interact with an organism

Nonliving parts of an organism’s habitat

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

All the members of one species living in a particular area referred to as a population.

All the different populations that live together in an area make up a community.

The community of organisms that lives in a particular area, along with the non living environment, make up an ecosystem.

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

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.

An organism that can make its own food

Obtains energy by feeding on other organisms

Break down biotic wastes and dead organisms

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

Consist of many overlapping food chains in an ecosystem

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

The set of chemical reactions plants use to turn light, water, and nutrients into oxygen and energy

An organism than makes its own food is known as an autotroph

An organism that has to get its food from a source and is unable to make its own food

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.

A relationship in which both species benefit

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

It shows how an organism obtains its food, the type of food the organism eats.

The struggle between organisms to survive as they use the same limited resources

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