Decomposers contribute to ecosystem nutrient cycles by:

Explanation:
Decomposers drive nutrient cycles by mineralizing organic matter into inorganic nutrients that plants can take up. They break down dead organisms and waste, converting complex carbon compounds into simpler inorganic forms such as ammonium, nitrate, and phosphate. This recycling makes essential nutrients available again for producers, keeping the cycle moving. Oxygen production comes from photosynthetic organisms, not decomposers; nitrogen fixation is carried out by specialized bacteria that convert nitrogen gas to usable forms, and nutrients aren’t transported through a bloodstream in ecosystems.
