Food web

• A visual model that shows how energy is transferred from one organism to another; contains overlapping food chains

• A linear sequence of organisms where each is eaten by the next

• A diagram that represents the flow of nutrients in an ecosystem

• A chart that lists all the species in a habitat without showing their interactions

Consumer

• Any organism that can make its own food.

• Any organism that depends on eating other organisms for its energy needs.

• Any organism that only eats plants.

• Any organism that can survive without food.

Fossil

• Preserved evidence from millions of years ago that shows the types of living things and their environment at that time

• A type of rock formed from volcanic activity

• A living organism that has existed for a short period

• A modern-day animal that has not changed over time

Biotic

• Parts of an ecosystem that are, or once were, alive

• Non-living components of an ecosystem

Producer

• An organism that performs photosynthesis to create its own food; often consumed for food by other organisms

• An organism that consumes other organisms for energy

• An organism that decomposes organic material

• An organism that relies on external sources for food

Abiotic

• Parts of an ecosystem that are not, and were never, alive
