Which of the following statements are correct ? (a) Energy flow...
Which of the following statements are correct ?
(a) Energy flow from producers to consumers is unidirectional
(b) Energy pyramid can never be inverted
(c) Transfer of energy follows the 1% law
Choose the correct answer from the options given below :
(a) Energy flow from producers to consumers is unidirectional
(b) Energy pyramid can never be inverted
(c) Transfer of energy follows the 1% law
Choose the correct answer from the options given below :
Options
- A(b) and (c) only
- B(a), (b) and (c)
- C(a) and (b) only
- D(a) and (c) only
Correct answer
C. (a) and (b) only
Step-by-step solution
Statement (a) is correct because energy flow in an ecosystem is strictly unidirectional, moving from producers to herbivores and then to carnivores. Energy cannot flow back in the reverse direction.
Statement (b) is correct because the pyramid of energy is always upright and can never be inverted. At each successive trophic level, a significant amount of energy is lost as heat to the environment.
Statement (c) is incorrect because the transfer of energy from one trophic level to the next follows the 10% law (Lindeman's law), not the 1% law. The 1% law applies only to the amount of incident solar radiation captured by plants (producers).
Therefore, only statements (a) and (b) are correct.
Answer: (a) and (b) only
Statement (b) is correct because the pyramid of energy is always upright and can never be inverted. At each successive trophic level, a significant amount of energy is lost as heat to the environment.
Statement (c) is incorrect because the transfer of energy from one trophic level to the next follows the 10% law (Lindeman's law), not the 1% law. The 1% law applies only to the amount of incident solar radiation captured by plants (producers).
Therefore, only statements (a) and (b) are correct.
Answer: (a) and (b) only
