LIFE SCIENCE

Detailed explanation-1: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-2: -Environmental factors that influence populations are divided into two categories – abiotic and biotic factors. Abiotic factors refer to the non-living physical and chemical elements found in an ecosystem such as rainfall, temperature, pH, sunlight, shelter and day length.

Detailed explanation-3: -Abiotically, population size can be regulated through natural disasters like floods, tornadoes, etc or things that affect climate like rain and temperature. Biotically, population size can be regulated by food and/or natural predators.

Detailed explanation-4: -Summary. Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths.
