Food Pyramid
A diagram that shows the amount of energy that moves from one trophic level to another in a food web.
Food Web
A patterns of overlapping food chains in an ecosystem.
Herbivore
A plant-eating animal.
Scavenger
An animal that feeds on the bodies of dead organisms.
Prey
An animal that is hunted and killed by another for food.
Predation
An interaction in which one organism kills and eats another.
Heterotroph
An organism that cannot make its own food and gets food by consuming other living things.
Autotroph
An organism that makes its own food.
Primary Producer
An organism that makes its own food.
Consumer
An organism that obtains energy by feeding on other organisms (plants and animals).
Omnivore
Animal that eat both plants and animal food.
Carnivore
Animal that obtains energy by eating only animals.
Predator
Any animal that lives by killing and eating other animals.
Algae
Besides plants,name another type of organism that is a producer.
Detritivores
Consumers of non-living (dead) organic matter including leaf litter and dead bodies.
Food Chains
Energy links between different organisms in an ecosystem based on feeding habits.
10%
How much energy is available for the next trophic level?
Decomposer
Organism that breaks down dead organisms into simpler parts.
Tertiary Consumer
Organisms that eat secondary consumers
Trophic Level
The position of an organism in relation to the flow of energy and nutrients through an ecosystem (e.g., producer, consumer, and decomposer).
Photosynthesis
The process in which organisms use water along with sunlight and carbon dioxide to make food.
Fungi and Bacteria
Two species that are decomposers
The direction of the flow of energy
What is indicated by the arrows in a food web?
Producer Trophic Level

Trophic Level 2
What trophic level are primary consumers located?
Lion
Which organism receives the least amount of energy from the producers?
Phytoplankton
Which producer is the basis of the marine food web?
