Question

value: 2
in a healthy ecosystem, what factors help to maintain relatively stable populations of different organisms?
○ a. abundant resources for all species
○ b. predator - prey relationships
○ c. competition for resources
○ d. all of the above

Explanation:

• Abundant resources: Provide the necessary materials (like food, water, shelter) for organisms to survive and reproduce, which is a basic requirement for population stability.
• Predator - prey relationships: Predators control prey populations. When prey are abundant, predators have more food and their population can increase. As predators increase, they consume more prey, reducing the prey population. Then, with less food, the predator population may decrease. This cycle helps maintain a balance.
• Competition for resources: Organisms compete for limited resources. This competition can prevent any one population from growing too large. For example, if two plant species compete for sunlight, water, and nutrients in the soil, neither will be able to over - dominate the ecosystem.

Since all of these factors (abundant resources, predator - prey relationships, and competition for resources) play important roles in maintaining relatively stable populations of different organisms in a healthy ecosystem.

Answer:

d. All of the above
