What is the main characteristic of biotic factors in an ecosystem?

The main characteristic of biotic factors in an ecosystem is that they involve living organisms and their interactions. Biotic factors encompass all the living components of an ecosystem, including plants, animals, fungi, and microorganisms. These organisms interact with one another in various ways, such as through predation, competition, symbiosis, and mutualism, which can greatly influence the structure and dynamics of the ecosystem.

The influence of biotic factors is crucial to the survival of species, as these interactions can affect resource availability, reproduction, and population dynamics. For instance, herbivores depend on plants for food, while predators rely on prey species for sustenance. Thus, understanding biotic factors is essential for comprehending the complexity of ecosystems and how living organisms coexist and evolve within them.
