Question

my answer was D but the answer is A can someone explain why

8. Each letter represents a different population, lado and shows the current size of each population. The growth of which population is most limited by its biotic potential (IN)? A) A B) B CC D D Population size, d = N(M) TimeOLE

Answer 1

This is a logistic growth curve.A population growing in a habitat with limited resources show initially a lag phase followed by phase of acceleration and deceleration and finally an asymptote,when population density reaches carrying capacity.

N=population density at time t

r=intrinsic rate of natural increase

K=carrying capacity

r=birth rate - death rate

In the graph it is clear that A follows lag phase.Here population size is less compared to others.Therefore rN will be a small value.D has the largest population size.Carrying capacity is the max population size an environment can hold.
