Question

Which is an example of environmental stochasticity? Check all that appy

Answer 1

Answer: All of the Above

Explanation:

Environmental stochasticity refers to unpredictable spatiotemporal alterations in extrinsic environmental conditions.

However, the variation in population dynamics across patches for the purpose of risk spreading can be described as indication of spatiotemporal flunctuation.

Moreover, activities within a population that are random and unpredicted and are demonstrated by individual behaviors causing migration in or out of a population, is one of effects of spatiotemporal fluctuation in environment.

Furthermore, events such as floods, droughts, and other natural catastrophe that may impose threat to a population spatial distribution, are also important examples of environmental stochasticity

Thus, all the above mentioned environmental effects pose a threat to the population of organims and all can be described as environmental stochasticity.

Answer 2

Answer:

1. Variation in individual health that affects likelihood of death.

2. Forest fires that kill large numbers of individuals every 10 to 50 years.

Explanation:

Environmental stoichasticity is an evolution and ecological literature that refers to the unpredictability of  fluctuation on the environment condition at various time and place. It is the unpredictable spatiotemporal fluctuation of the condition of the environment. Here the environment means both biotic and abiotic components of an environment. It reflects the fluctuations that occur in a population of species in a place and over a period of time.
