Question

PLEASE HELP ONLY IF YOU KNOW! THANKS!

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?

a) The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
b) The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
c) The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
d) The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.

Answer 1

The correct statement is B) The ecosystem with greater species diversity is more stable and likely to withstand the drought.

Step-by-step explanation:

An ecosystem is a dynamic and interconnected community of living organisms, along with their physical environment, interacting as a functional unit. It encompasses various species, their habitats, and the intricate relationships between them. Ecosystems range from terrestrial to aquatic, showcasing the delicate balance that sustains life and ecological processes.

The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought. High species diversity provides a greater range of traits and adaptations that can help organisms survive in different environmental conditions, including drought. This diversity allows for different species to fill ecological niches and can increase overall ecosystem resilience.
