Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Detailed explanation-2: -Decomposers also release organic compounds and carbon dioxide when they break down dead organisms and waste products.

Detailed explanation-3: -Decomposers, like fungi and bacteria, complete the food chain. Decomposers turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. They complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs.

Detailed explanation-4: -Expert-Verified Answer. The organisms that release carbon dioxide as waste are known as consumers and decomposers (option 2). Animals and humans that eat plants as a significant source of nutrients are referred to be consumers.

Detailed explanation-5: -Producers use energy and inorganic molecules to make food. Consumers take in food by eating producers or other living things. Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.
