Question

walking through a forest, one may encounter fallen leaves, dead organisms, a rotting stump. what can all of these be described as?

fungi

autotrophs
detritus

Explanation:

• Fungi: These are organisms (like mushrooms) that decompose organic matter. Fallen leaves, dead organisms, and a rotting stump are not fungi themselves.
• Autotrophs: These are organisms (like plants) that produce their own food through photosynthesis. Fallen leaves (when dead), dead organisms, and a rotting stump are not autotrophs.
• Detritus: This refers to dead organic material. Fallen leaves, dead organisms, and a rotting stump all fit this definition as they are parts of the dead organic matter in an ecosystem.

Answer:

detritus
