Abiotic and Biotic Resources Differences in Biology Import Concepts Must to Know
Question. Difference between Abiotic and Biotic Resources.
Answer:
Biotic:
The term βbioticβ is formed by the combination of two terms, βbioβ meaning life and βicβ 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.
Abiotic:
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.
Differentiating Property | Abiotic Resources | Biotic Resources |
Meaning | They are the non-living things present in an ecosystem. | They are the living things that make up an ecosystem. |
Dependency | Do not depend on biotic factors to exist. | Depend on abiotic factors for surviving and growing. |
Impact | Affects the individual of a specific species, their population, community, ecosystem, and biosphere. | Affects the biome, individual of a specific species, biosphere, and population. |
Measurement | It is objective. | It is subjective. |
Adaptation | Cannot adapt as per the environmental conditions. | Can adapt to the changes in the environment. |
Components | They include soil, topography, climate, and natural disturbances of an ecosystem. | They include different plants, animals, bacteria, algae. |
Origin | Originate from the lithosphere, hydrosphere, and atmosphere. | Originate from the biosphere. |
Example | Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity, precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc. | Humans, wild animals, birds, insects, bacteria, etc. |
Factors involve | The abiotic factors generally help in developing the cycle of the ecosystem in external terms for example sunlight is the basic requirement for plants during photosynthesis. So, they are involved with biotic in some or another way. | In the biotic category, we generally see that they help in forming a cycle in the ecosystem by producing and reproducing and gradually building up the cycle. |
Affects | Abiotic indirectly affects both ecosystems as well as a life cycle. | Biotics directly affects the ecosystem as well as the life cycle in the ecosystem and life cycle. |
