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

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

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

These are nonliving parts of an organisms habitat these physical components, include water, oxygen space, rocks, and light temperature

All the members of one species living in a population area

All the different populations that live together in area

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

The largest population that an area can support

Is a group of organisms that can mate with each other and produce offspring that can also mate and reproduce

An organism that can make its own food

Obtains energy by feeding on another organism

Break down biotic factors wastes and dead organisms

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

Consists of many overlapping food chains

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

Is any relationship in which 2 species live close together

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

Is a relationship in which both species benefit

Is a relationship that involves one gram living with on or inside another organism and harming it

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