How does the food chain start again after the decomposer does its' job? A) because the decomposer spreads the seeds B) because the decomposer must constantly stay busy to stay alive C) because the decomposer breaks the dead or decaying organism down and the nutrients go back into the soil, causing any seeds that have been dispersed a good environment to reproduce D) because the decomposer does not totally break the organism down and some of the organism is still alive
What is C, because the decomposer breaks the dead or decaying organism down and the nutrients go back into the soil, causing any seed that have been dispersed a good environment to reproduce?
