An organism gets 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

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

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 in an area

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

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

The number of individuals in an area of a specific size

A population to stop growing or to decrease in size, such as a fatal disease infecting organisms

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

Is a series of events in which one organisms eats another and obtains energy and nutrients

Consists 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

A set of chemical reactions plants use to turn light , water, and nutrients into oxygen and energy, in the form of sugars

Absorbs light, much like cells in solar panels do

Takes place among organisms every day

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

An interactions in which one organisms kills another for food or nutrition

Any relationship in which two species live closely together

Is a relationship in which one species benefits and other species is neither helped nor normal

Which is a relationship in which both species benefit

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

Consumers that eat both plants and animals

Consumers that only eat animals
