Abiotic Factor is a nonliving condition or thing, as climate or habitat, that influences or affects an ecosystem and the organisms in it:
Abiotic factors can determine which species of organisms will survive in a given environment.
Explanation:
Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect survival and reproduction process.
Furthermore, both these components are reliant on each other. Suppose if one of the factors is removed or altered, its repercussions will be faced by the entire ecosystem. Without a doubt, abiotic factors directly affect the survival of organisms.
Biotic Meaning
The term “biotic” is formed by the combination of two terms, “bio” meaning life and “ic” meaning like. Thus the term means life-like and is related to all the living entities present in an ecosystem.
Biotic Factors
Biotic factors relate to all the living things in the ecosystem. Their presence and their biological by-products affect the composition of an ecosystem. Biotic factors refer to all living organisms from animals and humans, to plants, fungi, and bacteria. The interactions between various biotic factors are necessary for the reproduction of each species and to fulfil essential requirements like food, etc.
Examples of Biotic Factors
The examples of biotic resources include all the living components present in an ecosystem. These include producers, consumers, decomposers and detritivores.
Abiotic Meaning
The term abiotic refers to all the non-living factors present in an ecosystem. Sunlight, water, land, all constitute the abiotic factors.
Abiotic Factors
Abiotic factors refer to all the non-living, i.e. chemical and physical factors present in the atmosphere, hydrosphere, and lithosphere. Sunlight, air, precipitation, minerals, and soil are some examples of abiotic factors. These factors have a significant impact on the survival and reproduction of species in an ecosystem.
For instance, without an adequate amount of sunlight, autotrophic organisms may not be able to survive. When these organisms eventually die, it will create a shortage of food for primary consumers. This effect cascades up the food chain, affecting every organism. Consequently, it leads to an imbalance in the ecosystem.
Examples of Abiotic Factors
Abiotic examples typically depend on the type of ecosystem. For instance, abiotic components in a terrestrial ecosystem include air, weather, water, temperature, humidity, altitude, the pH level of soil, type of soil and more. Abiotic examples in an aquatic ecosystem include water salinity, oxygen levels, pH levels, water flow rate, water depth and temperature.
