What is the primary function of saprobes in an ecosystem?

The primary function of saprobes in an ecosystem is to absorb nutrients from nonliving matter. Saprobes, also known as decomposers, play a crucial role in the breakdown of organic material, such as dead plants, animals, and other organic wastes. By breaking down this material, saprobes convert complex organic compounds into simpler forms, making nutrients available for other organisms in the ecosystem.

This nutrient recycling is essential for maintaining the health of ecosystems, as it ensures that vital elements such as carbon, nitrogen, and phosphorus are returned to the soil and can be utilized by primary producers, like plants. Without saprobes, ecosystems would become overloaded with dead matter, leading to nutrient depletion and decreased biodiversity.

The other options describe different ecological functions or roles but do not pertain specifically to the function of saprobes. For instance, photosynthesis is a process carried out primarily by plants and some microorganisms. Similarly, symbiotic relationships involve interactions between living organisms, while creating habitats refers to the physical structures provided by specific organisms, such as corals or trees, rather than the nutrient absorption function typical of saprobes.
