Provide one example of a density-dependent growth factor, and
one density independent growth factor.
, 4 | Page
Density dependent factors are directly related to the density of a
population,
and include immigration, emigration, birth rate and death rate. Density
independent factors do not directly relate to the density of a population,
and
include things like chance weather, and extreme events like drought,
flooding, etc.
A bird species nests in a specific kind of tree. The tree is not harmed

a. mutualism.
b. endosymbiosis.
c. commensalism.
d. symbiosis. commensalism
Which statement is true?
a. All pathogens are parasites.
b. All parasites are pathogens.
c. All symbionts are parasites.
d. Both a and b
All pathogens are parasites.
Two species of mice feed on berries. The mice are active at different
times of the day and do not come into contact with one another.
Nonetheless, the presence of one species limits the survival and
reproduction of the other. What type of competition is this?
a. Interference
b. Exploitation
