An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: Biotic components of the ecosystem continuously require energy to carry on life processes.
Reason: Abiotic components are the nonliving factors of the ecosystem.
The correct answer is option B.
Explanation:
Biotic Components Require Energy:
- The biotic components of an ecosystem include all living organisms such as plants, animals, and microorganisms.
- These organisms require energy to carry out various life processes such as growth, reproduction, movement, and metabolism.
- Energy is obtained through various sources such as sunlight, organic matter, or other organisms.
- Green plants, for example, use sunlight to carry out photosynthesis and convert it into chemical energy in the form of glucose.
- Animals, on the other hand, obtain energy by consuming plants or other animals.
Abiotic Components of Ecosystem:
- Abiotic components are the nonliving factors of an ecosystem.
- They include physical and chemical factors such as sunlight, temperature, water, air, soil, and minerals.
- These factors provide the necessary conditions for the survival and functioning of the biotic components.
- While abiotic components do not require energy for their own life processes, they play a crucial role in determining the availability of resources and environmental conditions for the biotic components.
Relationship between Assertion and Reason:
- The assertion states that biotic components of the ecosystem continuously require energy to carry on life processes, which is true.
- The reason states that abiotic components are the nonliving factors of the ecosystem, which is also true.
- However, the reason does not provide a direct explanation for why biotic components require energy.
- The reason simply provides additional information about the nature of abiotic components and their role in the ecosystem.
- The requirement of energy by biotic components is primarily due to their physiological processes and the need to maintain their biological functions.
Therefore, both the assertion and reason are true, but the reason is not the correct explanation of the assertion. Hence, option B is the correct answer.
