Population Size in Food Chains — NEET Biology

Which of the following statements regarding energy flow and decomposition in an ecosystem are NOT correct? S1: Solar energy, the ultimate source for most ecosystems, is captured by plants, which convert less than 50% of the incident solar radiation into Photosynthetically Active Radiation (PAR). S2: Only about 2-10% of the Photosynthetically Active Radiation (PAR) captured by producers is passed on to primary consumers. S3: Decomposers mineralize dead organic matter, making inorganic nutrients available for reuse by autotrophs, thereby ensuring nutrient recycling. S4: The entire energy trapped by producers, once it leaves the consumer trophic levels, is recycled back to the producers by decomposers. S5: In a terrestrial ecosystem, the detritus food chain typically accounts for a much larger fraction of energy flow compared to the grazing food chain.
