Which of the following statements is incorrect?
Which of the following statements is incorrect?
Options
- ABiomass decreases from first to fourth trophic level
- BEnergy content gradually increases from first to fourth trophic level
- CNumber of individuals decreases from first trophic level to fourth trophic level
- DEnergy content gradually decreases from first to fourth trophic level
Correct answer
B. Energy content gradually increases from first to fourth trophic level
Step-by-step solution
The pyramid of energy is always upright because the flow of energy is unidirectional from producer to consumer level. The energy content is maximum in producers. The energy decreases at each trophic level of food chain, as part of the energy is lost as heat and major part of energy is liberated during respiration for use in various activities.
Biomass decreases from first to fourth trophic level in an upright pyramid.
Number of individuals decreases from first trophic level to fourth trophic level in an upright pyramid.
