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

Parts of a habitat that are or once alive and that interact with an organism

The nonliving parts of an organisms 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

All the different populations that live together

The community of organisms that lives in a particular area, along with the nonliving environment

The study of how organisms interact with each other

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

The number of individuals in an area of a specific size

The largest population that an area can support

Organisms in there movement of energy

An organism that can make its own food

Obtains energy by feeding on other organisms

Consumers that only eat animals

Carnivores that feeds on the body of dead animals

Consumers that eat both plants and animals

They are things that break 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

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 that makes its own food is known

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

How an organism obtains it food, the type of food the organism eats

Takes place among organism every day

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

In this interaction, one organism is the predator and the other is the prey

Any relationship in which two species live closely together

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

A relationship ship in which both species benefit

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