Question

which organisms obtain energy from dead or decaying matter? select two options.
□ groundhogs
□ daisies
□ earthworms
□ bacteria
□ humans
□ phytoplankton

Explanation:

• Groundhogs are herbivores/omnivores that eat live plants or other organisms, not dead matter.
• Daisies are producers (photosynthesize) and don't consume dead matter.
• Earthworms decompose organic matter in soil, breaking down dead material.
• Bacteria (decomposer bacteria) break down dead/decaying matter to obtain energy.
• Humans are consumers (eat live or processed food, not typically dead/decaying matter as a primary energy source).
• Phytoplankton are producers (photosynthesize) and don't consume dead matter.

So the two organisms that obtain energy from dead or decaying matter are earthworms and bacteria.

Answer:

C. earthworms, D. bacteria
