Question

1. density - independent factor would include all of the following except *

drought
fires
predation
flooding
all of the above are density - dependent

1. which would be least likely to be affected by a density - dependent limiting factor?

a small, scattered population
a population with a high birth rate
a large, dense population
a population with a high immigration rate
none of the above

Explanation:

1. Density - independent factors affect populations regardless of density. Drought, fires, and flooding are natural disasters that impact populations without regard to how dense they are. Predation is density - dependent as predators are more likely to find prey in denser populations.
2. Density - dependent factors such as competition for resources, predation, and disease have a greater impact on large, dense populations. A small, scattered population is less likely to be affected by these factors as there is less competition and less contact between individuals.

Answer:

1. C. Predation
2. A. A small, scattered population
