Answer 1

One natural factor that may limit human population growth is resource competition. Pollution, such as the accumulation of smog clouds over cities, can have a detrimental effect on plant life below the cloud.

Step-by-step explanation:

(a) One natural factor that may limit human population growth is resource competition. As the population increases, the demand for resources such as food, water, and space also increases. Eventually, there may not be enough resources available to support the growing population, leading to a decrease in population growth.

(b) The accumulation of large clouds of smog over cities as a result of pollution can have a detrimental effect on plant life below the cloud. The smog contains pollutants like sulfur dioxide and nitrogen oxides, which can damage the leaves and reduce photosynthesis. This can result in stunted growth, reduced crop yields, and even death of plant life.
