Biology · Secondary 4 · Medium · Energy flow in ecosystems
In a simple food chain in a mangrove swamp,
mangrove leaves → snails → crabs → herons
Only about 10% of energy is transferred from one trophic level to the next. If the mangrove leaves receive 20 000 kJ of energy, approximately how much energy is available to the crabs?
