Questions and Answers
What is the difference between a detritivore and a decomposer?
While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.

Study Notes
Cycling of Matter and Energy
-
Detritivores vs. Decomposers:
- Detritivores consume dead organic matter while decomposers break down dead or decaying organisms into simpler substances.
-
Food Chains vs. Food Webs:
- Food webs consist of complex networks of interrelated food chains, illustrating multiple feeding relationships within an ecosystem.
-
Heterotrophs Defined:
- Heterotrophs are organisms that rely on consuming other organisms (plants and animals) to obtain energy, distinguishing them from autotrophs, which produce their own energy.
-
First Trophic Level:
- Autotrophs, such as plants and photosynthetic organisms, represent the foundational trophic level in ecosystems, serving as primary producers.
-
Matter and Energy Relationship:
- Matter and energy continuously cycle through ecosystems, facilitating various biological processes and supporting life.
