Biotic means related to living things or life —either living organisms themselves or things produced by them (like waste, remains, or secretions).

Quick Scoop: Core Meaning

  • In biology, “biotic” refers to all living or once-living components of an environment, such as plants, animals, fungi, and microbes.
  • As a word, it’s an adjective meaning “of, relating to, or caused by living organisms.”
  • It comes from Greek roots meaning “pertaining to life.”

If something involves life, living things, or their remains, it’s probably biotic.

Biotic vs Abiotic (The Classic Pair)

Biotic is almost always explained together with abiotic.

  • Biotic factors: living things in an ecosystem (plants, animals, bacteria, fungi, etc.).
  • Abiotic factors: non-living parts of the environment (light, temperature, soil, water, air, rocks).

In a forest, for example:

  • Biotic: trees, insects, birds, fungi, moss, bacteria in the soil.
  • Abiotic: sunlight, rainfall, temperature, rocks, nutrients in the soil.

These interact constantly: living things depend on abiotic conditions, and their activities (like decomposing organic matter) change those conditions.

Mini Story: A “Biotic” Day in a Pond

Imagine a small pond near your house.

  • Algae and water plants use sunlight to make food.
  • Tadpoles eat algae; fish eat insects and tadpoles.
  • Bacteria break down dead leaves and dead fish, returning nutrients to the water and mud.

All of these organisms and their remains (slimy film, waste, dead leaves) are biotic parts of the pond.

The water itself, the sunlight, the temperature, and the mud minerals are abiotic.

Where You’ll See “Biotic” Used

You’ll often meet the word in school, science news, or online discussions like:

  • “Biotic factors in this ecosystem include plants, herbivores, carnivores, and decomposers.”
  • “Biotic community” = all interacting living organisms in a habitat.
  • “Biotic potential” = how fast a species could reproduce under ideal conditions.

In short: when you see “biotic” in biology or ecology, think “living things and what they do.”

TL;DR:
“Biotic” = anything involving living organisms or their products, usually contrasted with non-living “abiotic” factors in an environment.
