A
Process plants use to make their own food
photosynthesis
Shows the transfer of energy between organisms in an ecosystem
food chain
The amount of energy that is passed to each level
10%
Green pigment that enables a plant to absorb sunlight
chlorophyll
Examples of these are fungi, bacteria, and earthworms
decomposers
Community of organisms and the environment they live in
ecosystem
Source of energy for producers
sun
Bottom trophic level of an energy pyramid
producers
Consumer that gets its food energy by breaking down the remains of dead organisms
decomposer
Important byproduct of photosynthesis
oxygen
Animal that eats only producers
herbivore
First level consumers (plant eaters)
herbivore
The first trophic level after producers
primary level
Shows the relationship among overlapping food chains
food web
People breathe out this gas that plants take in during photosynthesis
carbon dioxide
Organism that makes its own food
producer
2nd level consumers (meat eaters)
carnivore
The top level of an energy pyramid
tertiary level
The number of animals that live in the same environment
populations
Animal that eat both plants and other animals
omnivore
An organism that eats things
consumer
Top level consumer (bears, people)
omnivore
The amount of energy used at each level for life processes
90%
