Question

1. a limiting factor that depends on population size is called a

a. density - dependent limiting factor.
b. density - independent limiting factor.
c. predator - prey relationship.
d. parasitic relationship.

Explanation:

• Density - dependent limiting factors are influenced by population size. For example, competition for resources (food, space) increases as population density (a measure related to population size) goes up.
• Density - independent limiting factors (like natural disasters) are not related to population size.
• Predator - prey relationships are a type of interaction but not directly defined by dependence on population size in the way the question asks.
• Parasitic relationships are a form of symbiosis and not specifically about a limiting factor depending on population size.

Answer:

a. density - dependent limiting factor
