16. Which of the following best describes when a population has reached carrying capacity within an ecosystem

(A) Birth rate= death rate

(b) Population growth accuracy exponentially

(c) Organism are adjusting to new environmental conditions

(d) Birth rate exceed death rate

Expert Solution

The options provided are not at all-sufficient. The correct option would be - " population size decreases when the population size reaches the carrying capacity."

Explanation- Carrying capacity is the maximum number of individuals a region can hold i.e the maximum population size. But when the population size exceeds carrying capacity, the population size tends to decrease. This happens because there are multiple factors being acted upon the excess population. That is competition for food, insufficient space etc.

However. if only the 4 options provided are to be considered, then option A. Birth rate=death rate goes to the nearest.
Why not others-- b. Population does not exceed exponentially because it then tends to decrease.

c. organsims are not able to adjust because there are limitations of everything from food to shelter.

d. birth rate exceed death rate only when the population has a very low number of members.
