Consider the following food chain in a terrestrial ecosystem: Grass Grasshopper Frog Snake Hawk If 20,000 J of energy is available at the producer level, what will be the amount of energy available to the organism at the fourth trophic level?

Step-by-step solution

According to Lindeman's 10% law, only 10% of the energy is transferred from one trophic level to the next higher trophic level. The given food chain can be mapped to trophic levels as follows: First trophic level ( T₁ , Producer): Grass Second trophic level ( T₂ , Primary Consumer): Grasshopper Third trophic level ( T₃ , Secondary Consumer): Frog Fourth trophic level ( T₄ , Tertiary Consumer): Snake Fifth trophic level ( T₅ , Top Carnivore): Hawk Energy available at T₁ (Grass) = 20,000 J Energy available at T₂ (Gra
