Write down an example of a food chain and label one decomposer, one autotroph, one heterotroph, one consumer, one producer, one carnivore, one herbivore, and one omnivore. 5. What is biomass? What part of a food pyramid contains the most biomass? The least? 6. In the food chain you drew above, which trophic level contains the most available energy? Which trophic level contains the least? 7. How much energy is passed from one trophic level to the next? What happens to the rest of the energy, what does it mainly get released as? 8.
