Resources that control the Size of a population of organisms.
What are limiting factors/resources/nutrients?
300
The process of bacteria living on the roots of plants and change nitrogen gas into compounds that the plant can use.
What is nitrogen fixation?
300
Changes to an individual that are not controlled by genetic code, but rather the individual obtains through some sort of life activity.
What are acquired traits?
300
Advantage that sexually reproducing organisms have over asexually reproducing organisms.
