7. What would be a consequence of removing the decomposers from an ecosystem?
A Plants would not need to absorb nitrogen from the soil any longer
B Lightening would no longer convert nitrogen gas into ammonia
C Plants would begin decomposing organisms instead of performing photosynthesis
D Nitrogen would remain trapped in the tissues of dead organisms

D

Explanation:

Decomposers play the role of breaking down matter in an environment. Through breaking down matter, they release nutrients in the soil. If there weren't any decomposers, the nutrients would remain trapped inside dead organisms. Hope this helped :)))

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
