Which of the following pairs incorrectly matches a biotic component with its role in the ecosystem?
ADecomposers - Break down dead organic matter
BProducers - Convert sunlight into chemical energy
CHerbivores - Feed on plants
DConsumers - Produce their own food through photosynthesis
Step-by-Step Solution
  1. Step 1: Understand roles of biotic components

    Decomposers break down dead matter; producers (plants) perform photosynthesis; consumers eat other organisms; herbivores feed on plants.
  2. Step 2: Analyze each pair

    Decomposers breaking down dead matter is correct. Producers converting sunlight into chemical energy is correct. Consumers do not produce their own food; they consume others. Herbivores feeding on plants is correct.
  3. Step 3: Identify incorrect match

    The incorrect match is consumers producing their own food through photosynthesis, which is false.
  4. Final Answer:

    Consumers - Produce their own food through photosynthesis → Option D
  5. Quick Check:

    Consumers producing food = Incorrect ✅
Quick Trick: Only producers photosynthesize, not consumers.
Common Mistakes:
  • Confusing consumers with producers in food chains.
