In the following food chain, which organism has the highest energy level?
Grass→Squirrel→Fox→Lion
Grass
Plants can absorb the energy directly from the sun to perform photosynthesis. A part of their energy is transferred to the herbivores when they eat the plants. The carnivores eating the herbivores obtain a part of that energy from them. So, as we move up the trophic levels, the amount of energy transferred decreases. Hence, in the given food chain, grass has the highest energy and lion gets the least amount of energy.
