Question

All living organisms have basic needs. As a result, the number and kind of organisms that an ecosystem can support are limited by the available resources in that ecosystem. Which of the following is a living factor that influences the survival of an organism in an ecosystem?

amount of sunlight

other organisms

soil composition

temperature range

amount of water

Answer 1

The correct answer is other organisms. The presence or absence of predators, prey, competition, and symbiotic relationships all have a significant impact on the survival and success of an organism in an ecosystem. The other factors listed, such as sunlight, soil composition, temperature range, and amount of water, are abiotic or non-living factors that also play a role in determining the types and numbers of organisms present in an ecosystem.
