Question

why the number of organisms tends to rise above and fall below the carrying capacity in the above graph? due to limiting factors. due to the faster reproduction rate. due to decline in the population. due to faster increase in the number of individuals.

Explanation:

Carrying capacity is the maximum population an environment can sustain. Limiting factors (like food, space, resources) cause population to fluctuate around it: when resources are abundant, population rises above; when resources become scarce (due to limiting factors), population falls below. Faster reproduction rate, population decline, or faster individual increase don't explain the fluctuation around carrying capacity as directly as limiting factors do.

Answer:

A. Due to limiting factors.
