What type of factors are considered abiotic in an ecosystem?

Abiotic factors are the non-living components of an ecosystem that influence the environment and the organisms living within it. Weather conditions, such as temperature, precipitation, humidity, and wind, play critical roles in shaping the ecosystem. They affect the growth and distribution of organisms, influence the types of habitats that can exist in an area, and determine the overall health of the ecosystem.

In contrast, living organisms are categorized as biotic factors because they are the living components, including plants, animals, fungi, and microorganisms, that interact with one another. Human activities, while impacting ecosystems, are also not classified as abiotic; they represent biological and social actions that can cause environmental changes. Plant nutrients, although crucial for the growth of plant life, are considered biological interactions and thus do not fall under the abiotic category. Therefore, weather conditions are the correct choice as they represent the non-living, physical elements that affect the ecosystem.
