b. Plants that require the same limiting nutrient

c. Lions and hyenas that fight over a captured zebra

d. Zebra and and ants that both consume grass

3. In the logistic growth model describing intraspecific competition, as the population size increases and approaches the carrying capacity, K, the population growth rate will ____________. *

a. increase

b. decrease

c. remain unchanged as long as no other variables are changed

Answer 1

1. Interspecific and Intraspecific competition do not occur simultaneously.

Correct option is (c)

2. The rarity or absence of mussels is because of, both interference and exploitative competition.

Correct answer is (a)

3. In the logistic growth model, the population rate growth falls as the population size increases. when the carrying capacity is reached, the rate of change of population density falls to zero.

Correct option is (c)
