Detailed explanation-1: -A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

Detailed explanation-2: -Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

Detailed explanation-3: -Answer: An ecosystem includes different communities of plants, animals and microbes together with their physicochemical environments. It consists of two major components, biotic or living components and nonbiotic or nonliving components. Biotic components include plants, animals, decomposers.

Detailed explanation-4: -Ecology is the study of how living things interact with each other and with their environment. The environment includes abiotic (nonliving) and biotic (living) factors.

Detailed explanation-5: -Biotic factors are grouped by scientists into three major groups, which define their role in the flow of energy which all living things in the ecosystem need to survive. These groups are producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
