The absence of decomposers in the environment would lead to litter all around. Here's why:

Decomposers play a crucial role in the ecosystem by breaking down dead or decaying organisms. They are responsible for carrying out the process of decomposition, which returns vital nutrients back into the environment.

Without decomposers, these dead organisms would not be broken down and recycled into the ecosystem. This would result in a build-up of waste, or "litter," in the environment.

So, the correct answer is (b) litter all around.

The other options are incorrect because: a) The number of producers would not necessarily increase. Producers need nutrients in the soil to grow, and without decomposers, these nutrients would not be replenished. c) The environment would not be cleaner. In fact, it would be filled with the litter of dead and decaying organisms. d) Nature would not be replenished of nutrients. As mentioned, decomposers are needed to return nutrients to the soil. Without them, this process would not occur.
