Answer the following question given this paragraph: 

Decomposers are heterotrophs that break down the wastes of other organisms or the remains of dead organisms. When they do, they release simple inorganic molecules back into the environment. Producers can then use the inorganic molecules to make new organic compounds. For this reason, decomposers are essential to every ecosystem. Imagine what would happen if there were no decomposers. Organic wastes and dead organisms would pile up everywhere, and their nutrients would no longer be recycled.


Q: Without what food chain component, organic wastes and dead organisms would pile up everywhere, and their nutrients would no longer be recycled?

 Choices:

- acids

- probiotics

- nitrates
