Biotica

Biotica is a term used in ecology and biology to refer to the living components of an environment—the organisms themselves and their collective interactions. It is often used in contrast to abiotic factors, which are the nonliving physical and chemical elements such as climate, water, soil, and minerals. In many contexts biotica is synonymous with the biota or the living ecosystem, though usage can vary by language and discipline.

The biotic component includes all classes of organisms: producers such as plants and algae that convert energy into biomass, consumers including animals and some microbes that feed on others, and decomposers such as bacteria and fungi that break down organic matter. Biotic interactions are central to ecosystem function and include predation, competition, mutualism, parasitism, and commensalism. These interactions influence population dynamics, community structure, energy flow, nutrient cycling, and ecological succession.

Biotica varies across geographic regions and ecosystems, contributing to regional biodiversity and ecological resilience. Human activities—habitat alteration, climate change, introduction of invasive species, and pollution—can modify biotic communities, sometimes with cascading effects on ecosystem services such as food, clean water, and recreation.

In scholarly writing, biotica is sometimes used interchangeably with biota or as a broader descriptor for living components of an environment. Modern ecology often emphasizes biotic components alongside abiotic factors to assess ecosystem health, conservation needs, and environmental management.
