Final answer:
Examples of environmental stochasticity that make smaller populations more vulnerable to extinction include variations in predation, natural catastrophes, fluctuations in food supply, and diseases.
Step-by-step explanation:
Environmental stochasticity refers to fluctuations in the environment that can impact populations. Some examples of environmental stochasticity that make smaller populations more vulnerable to extinction include variations in predation, natural catastrophes, fluctuations in food supply, and diseases.
For example, a small isolated population may be more likely to be wiped out by a natural disaster like a flood or fire, while a larger population may have some individuals that survive and can recolonize the habitat. Similarly, a decline in food supply or an increase in predation can have a greater impact on a smaller population.
