What factor in an ecosystem may include temperature, sunlight, and water levels?

The correct answer is that temperature, sunlight, and water levels are examples of abiotic factors in an ecosystem. Abiotic factors refer to the non-living components that influence the environment and the organisms within it. These factors play a crucial role in shaping the habitat and determining the types of organisms that can thrive in a particular ecosystem.

Temperature affects the metabolic rates of organisms, sunlight is essential for photosynthesis and influences plant growth, and water levels determine the availability of freshwater resources for all living organisms. Each of these abiotic factors interacts with biotic factors, which are the living components of an ecosystem.

While the other options refer to elements of an ecosystem, they do not encompass non-living factors. For instance, biotic factors refer to living organisms, such as plants, animals, and microorganisms. Living components focus specifically on the interactions between these organisms, while organic factors typically pertain to substances derived from living matter. Understanding the distinction between abiotic and biotic factors is essential for grasping how ecosystems function and how living organisms adapt to their environments.
