The ability to do work or cause change

An organism that can make its own food through the process of photosynthesis

An organism that obtains energy by feeding on other organisms

A consumer that eats only plants

A consumer that eats only animals

An animal that eats both plants and animals

A carnivore that feeds on carrion, the bodies of dead organisms

Consumers that feed on the remains of plants, animals and other dead matter breaking them down into their basic substances. Also called a detritivore.

A series of events (one straight line) in which one organism eats another and obtains energy.

model that shows the complex network of feeding relationships within an ecosystem

a model that shows the amount of energy available in each link of a food chain

Each step in a food chain or food web

An organism that makes its own food through photosynthesis. aka producer

organism that obtains energy from the foods it consumes; aka consumer

A biological community of interacting organisms and their physical environment

conservation of matter

matter cannot be created or destroyed, only changed from one form to another

The continual movement of water between Earth's atmosphere, oceans, and land and living things

The change of a substance from a liquid to a gas

The change of a substance from a gas to a liquid

Any form of water that falls from clouds and reaches Earth's surface (rain, snow, sleet, hail)

the process by which oxygen is exchanged between living things on Earth and its atmosphere.

the process by which carbon moves within and between organisms and the physical environment
