Compare biotic and abiotic factors

Biotic and Abiotic are two factors in an ecosystem.

If a pond is taken as an example of an ecosystem that one can easily understand; then==

1) Biotic or living factors in that pond are = Fishes, aquatic plants, algae snails, slugs, and micro-organisms. Insects that visit the plants / flowers for pollination, fungi that bring about decomposition of dead organic mater are all Biotic.

2) Abiotic or non-living factors are = Soil / mud at the bottom,

water in the pond, its temperature and pH, the dissolved gases in the water, Sun shining in the sky and providing light.

These are all Abiotic.

Biotic: anything that's alive

Abiotic: everything that's non-living
