Answer:
Decomposes are essential to maintain the cycle of nutrient, mass and energy
Step-by-step explanation:
Decomposers lie at the highest trophic level of an ecosystem. When an organism lying at tertiary trophic level dies, the decomposers convert the dead remains of organisms into simpler organic compounds and elements which mix into the soil.
These simpler organic compounds and elements are taken up from the soil by the plants as nutrients essential for their growth. A well grown plants becomes capable to produce food for all other organism.
Thus, decomposes are essential to maintain the cycle of nutrient, mass and energy
