• Biotic Factors

• Abiotic Factors

The maximum number of individuals that an environment can support long term is...

• carrying capacity

• population density

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

Something that regulates the size of a population is called...

• a limiting measure

• a limiting factor

What are factors that affect carrying capacity?

• Biotic only

• Biotic and abiotic

• Abiotic only

Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.

• Heterotroph

• Autotroph

Organisms that get their energy and nutrition from other organisms (consumers).

• Autotroph

Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.

• Producer

• Decomposer

• Autotrooph

Heterotrophs that feed on the dead and decaying organisms.
