Definition of biotic factors and abiotic factors
The biotic factors are those having life, ie organisms such as bacteria, animals and plants. On the other hand, abiotic factors indicate those conditions that must be present for the survival of biotic factors (that is, plants, animals, fish, fungi, bacteria, insects, etc.). Thus, abiotic factors are, for example, air, water, light intensity, wind, land, etc.
Relationship between biotic factors and abiotic factors
The change in the atmospheric conditions of a certain ecosystem , for example, global warming, change in relation to the humidity of the place, etc. are conditions of abiotic factors (that is, without life) that modify biotic factors (that is, those that have life) and that, consequently, changes the ecosystem . But we must also point out that biotic factors influence and can alter abiotic factors . In conclusion, both biotic and abiotic factors have to be in balance but the alteration of one modifies the other.
Finally, it is important to clarify that abiotic factors are found in the physical environment, generating environmental conditions to facilitate the life of biotic factors, but also, many of these abiotic factors are found inside living beings, that is say inside the biotic factors. For example, water, oxygen and calcium are abiotic factors present inside the cells of living beings but they correspond to the category of abiotic factors.
