Biotic Factors
Biotic factors are the living components of an ecosystem. These include all the organisms, such as plants, animals, fungi, and microorganisms, that interact with one another within a specific environment.
Examples of Biotic Factors
Impact on Ecosystems
Biotic factors play a crucial role in shaping ecosystems. They contribute to the food web, help with nutrient cycling, and influence the physical characteristics of the environment. The interactions between biotic factors can have a significant impact on the overall balance and health of an ecosystem.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
