A biotic factor refers to any living component that affects or influences an ecosystem and the organisms within it. These factors include interactions with other living things such as competition, predation, disease, and symbiosis. Biotic factors shape the environment and determine the distribution and abundance of organisms. For instance, the presence of predators can limit the population size of prey species, and plants might compete for sunlight, water, and nutrients, affecting their growth and survival. Understanding these relationships helps GCSE Biology students to appreciate the complexity and interdependence of life in ecosystems.
