Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a limiting factor in a population of organisms
A
reproductive replacement
B
life spans of the members
C
fluctuations in atmospheric temperature
D
availability of food
Explanation: 

Detailed explanation-1: -Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

Detailed explanation-2: -Space, food, oxygen, and water are limiting factors. Temperature and precipitation determine the climate of an ecosystem, which impacts the organisms that can live in an ecosystem. An ecosystem can support only so large of a population.

Detailed explanation-3: -In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

Detailed explanation-4: -The common limiting factors in an ecosystem are food, water, habitat, and mate. The availability of these factors will affect the carrying capacity of an environment. As the population increases, food demand increases as well. Since food is a limited resource, organisms will begin competing for it.

Detailed explanation-5: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons.
