Question

Do you think microscopic organisms like bacteria and amoebas are impacted differently by the factors that limit population size differently than larger organisms like humans? Explain why or why not.

Answer 1

Answer:

Explanation:

Factors that limit population size of an organism and slows it down and prevents it from growing are called limiting factors. Limiting factors generally affects all living organisms with the same impact; this is because the mode of survival of living organisms (based on the characteristics of living things) are usually threatened by limiting factors BUT the responses are different.

For example, when there is low supply of food (which is a limiting factor), large organisms (like humans) emigrate from such region or location to a region where there is a large or enough supply of food thereby reducing the population of the that large organisms in the initial location. A short supply of food/nutrient for bacteria (which is also a limiting factor) is responded to differently. When there is a short supply of nutrient to a bacterial population, it affects the population size by restricting the growth of such bacteria in that space/location.
