What does biotic and abiotic factor mean?

Answer 1

Biotic factors are living creatures or their remains that have an effect on a given situation. Abiotic factors are nonliving, nonorganic items that have an effect on a given situation. For instance, in describing the loss of frogs from a pond, a biotic factor may be the introduction of a non-native species that hunted the frogs to local extinction. An abiotic factor may be an increase in water pH caused by increased sulfuric acid levels due to acid rain.
