Biotic and Abiotic Factors Activity



Biotic and Abiotic Factors Activity

Biotic and abiotic factors are interrelated. If one factor is changed or removed, it impacts the availability of other resources within the system.

Biotic Factors

Biotic, meaning of or related to life, are living factors. Plants, animals, fungi, protists and bacteria are all biotic or living factors.

Abiotic Factors

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.

A System

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.

The 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

ECOSYSTEM Activity

Abiotic and Biotic Factors – Sketch out a meter square for each location in the environments surrounding the school. List ALL of the abiotic and biotic factors in this ecosystem. On the back of this page complete a second location and repeat the steps.

Identify at least five relationships. Identify how a change in one abiotic factor would impact other factors in the ecosystem.

Create a sketch of your location
