Question

which of the following best matches the description? combination of all environmental influences that tend to keep populations stable. select one: a. immigration b. stable equilibrium phase c. age distribution d. death phase e. environmental resistance f. emigration g. exponential growth phase h. population density i. dispersal j. density - dependent limiting factor k. lag phase l. carrying capacity m. r - strategist n. density - independent factor o. biotic potential p. k - strategist

Explanation:

Environmental resistance is the combination of all environmental factors (biotic and abiotic) that act to limit the growth of a population and keep it stable. Immigration and emigration are related to movement of individuals into and out of a population. Age - distribution affects population structure but not the overall environmental influences on stability. Phases like stable equilibrium, exponential growth, death, and lag are population - growth phases. Population density is a measure of how many individuals are in a given area. Density - dependent and density - independent factors are part of environmental resistance but are more specific types. Carrying capacity is the maximum number of individuals an environment can support. r - strategist and K - strategist are types of life - history strategies. Dispersal is the movement of individuals away from their place of origin. Biotic potential is the maximum reproductive capacity of a population under ideal conditions.

Answer:

e. environmental resistance
