1
Q

abiotic

A

non-living elements of a habitat, such as wind, water, sunlight, temperature, rocks, soil and periodic disturbances, which are factors that have a direct affect on local species distribution

2
Q

autotrophic

A

organisms such as plants that can convert the sun’s energy into chemical energy that will be used by other living things Autotrophic organisms are called primary producers and are the base of any food chain

3
Q

biochemical

A

process that occurs in living things

4
Q

carnivore

A

consumers that obtain all of their nutritional requirements by eating other animals

5
Q

chemoautotroph

A

any organism that produces its energy from chemical compound oxidation, specifically organic compounds containing

6
Q

community

A

a geographic area that supports diverse species populations

7
Q

consumer

A

organisms unable to produce their own food; obtain all of their nutrition through consumption of other organisms

8
Q

decomposer

A

organisms that feed on and break down dead organisms to recycle nutrients back into the ecosystem

12
Q

heterotrophic

A

organisms that are unable to produce their own food and are reliant upon the consumption of other organisms

13
Q

metabolism

A

the living body’s chemical process for the transformation of energy in support of function and activity

14
Q

population

A

a group of organisms of the same species living in the same area

15
Q

primary producers

A

organisms that produce their own food; plants convert the sun’s energy into the chemical energy used by all living things
