Question: Which of the following type of nutrition is a decomposer most likely to utilize?

Decomposers are organisms that break down dead or decaying organic matter, such as plants and animals. They play a vital role in recycling nutrients and maintaining the balance of ecosystems. But how do decomposers obtain their energy and nutrients? What type of nutrition do they use?

There are two main types of nutrition: autotrophic and heterotrophic. Autotrophic nutrition is when an organism can make its own organic molecules from inorganic sources, such as carbon dioxide and water. Examples of autotrophs are plants, algae, and some bacteria that use photosynthesis or chemosynthesis. Heterotrophic nutrition is when an organism cannot make its own organic molecules and must obtain them from other sources, such as other organisms or organic matter. Examples of heterotrophs are animals, fungi, and most bacteria.

Decomposers are heterotrophs, meaning they rely on other sources of organic matter for their nutrition. However, not all heterotrophs are decomposers. Some heterotrophs are consumers, meaning they feed on living or recently killed organisms, such as herbivores, carnivores, and omnivores. Decomposers are different from consumers because they feed on dead or decaying organic matter, such as fallen leaves, dead animals, or feces.

Decomposers use different methods to break down organic matter. Some decomposers, such as fungi and some bacteria, secrete enzymes that digest the organic matter externally and then absorb the nutrients. This is called extracellular digestion. Other decomposers, such as earthworms and some insects, ingest the organic matter and digest it internally in their digestive system. This is called intracellular digestion.

Therefore, the type of nutrition that a decomposer is most likely to utilize is heterotrophic nutrition with extracellular or intracellular digestion, depending on the decomposer.
