When does the exponential growth of a population start to slow down?

Exponential growth of a population start to slow down when there is a competition for resources.

An environmental niche plays a big role in the population decline rate. We must think of an environmental niche as a profession for organisms (what it does for the environment, how it responds, how resources are used, etc.) when a niche is occupied by multiple species competition amongst them occur.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
