Final answer:
Decomposers do indeed put phosphorus and nitrogen back into the soil when decomposing animal waste and dead organisms.
Step-by-step explanation:
Decomposers play a crucial role in recycling nutrients back into the soil. When decomposing animal waste and dead organisms, decomposers release nutrients such as phosphorus and nitrogen back into the environment.
These nutrients are recycled and can be taken up by plant roots, ensuring that producers have enough nutrients to thrive.
