and Abiotic Factors
and abiotic factors are interrelated. If one factor is changed
or removed, it impacts the availability of other resources
within the system.
meaning of or related to life, are living factors. Plants,
animals, fungi, protist and bacteria are all biotic or living
Abiotic, meaning not alive, are nonliving factors that affect
living organisms. Environmental factors such habitat (pond,
lake, ocean, desert, mountain) or weather such as temperature,
cloud cover, rain, snow, hurricanes, etc. are abiotic factors.
Biotic and abiotic factors combine to create a system or more
precisely, an ecosystem. An ecosystem is a community of living
and nonliving things considered as a unit.
Impact of Changing Factors
If a single factor is changed, perhaps by pollution or natural
phenomenon, the whole system could be altered. For example,
humans can alter environments through farming or irrigating.
While we usually cannot see what we are doing to various ecosytems,
the impact is being felt all over. For example, acid rain
in certain regions has resulted in the decline of fish population.
