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

The non living parts of and organisms habitat

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

The community of organisms that lives in a particular area along with the non living 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

An environmental factor that causes a population to stop growing or to decrease

The largest population that an area can support

An organism that can make its own food

Obtains energy by feeding on other animals

Break down biotic waste and dead organisms

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

Consists of many overlapping foods chains in an ecosystem

Shows the amount of energy that moves from one feeding level to another

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

Absorbs light much like the cells in a solar panels do

An organism that makes its own food

An organism that has to get its food from a source

Consumers that only eat animals

A carnivore that feeds on the bodies of dead organisms

Consumers that eat only plants and other photosynthetic organisms

Consumers that eat both plants and animals

How an organism obtains its food, the type of food the organism eats, and what other organisms eat it

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

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 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
