Which best describes the ecosystem at Point C?
O A. There are plenty of resources.
B. Population growth is exponential
O c. The beetles are competing for resources
O D. It has not reached carrying capacity

The correct answer is option C.

Explanation:

The graph shows that a controlled population of beetles, where other individuals do not leave or enter, experiences progressive growth from point A to C and plateau over time. This is because the population has sufficient resources to guarantee their development, the birth rate increases than the rate of mortality and there is no competition for these resources.

The adequate amount of resources allows that at point C, the carrying capacity is almost reached, which is the result of competition among members of the same species, which ensures that the net population growth rate is going to decrease or go stable due to limited resources..

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.
