Question:medium
Given below are two statements:
Statement I: The primary source of energy in an ecosystem is solar energy.
Statement II: The rate of production of organic matter during photosynthesis in an ecosystem is called net primary productivity (NPP).
In light of the above statements, choose the most appropriate answer from the options given below:

Statement II: The rate of production of organic matter during photosynthesis in an ecosystem is called net primary productivity (NPP).
In light of the above statements, choose the most appropriate answer from the options given below:
Show Hint
Net primary productivity (NPP) is an important ecological measure that indicates the amount of energy available for consumers in an ecosystem after accounting for the energy used by producers themselves.

- Both Statement I and Statement II are incorrect
- Statement I is correct but Statement II is incorrect
- Statement I is incorrect but Statement II is correct
- Both Statement I and Statement II are correct
Hide Solution
The Correct Option is D
Solution and Explanation
Both statements are accurate.
Statement I: Solar energy is indeed the principal energy source for the majority of ecosystems. Plants harness this energy through photosynthesis, establishing the base of the food web.
Statement II: The measure of organic matter generated via photosynthesis within an ecosystem, after deducting energy consumed through respiration, is termed net primary productivity (NPP).
Consequently, both statements are validated.
