Question

based on the food chain in the diagram, select the statement(s) that accurately describe the living organism as an autotroph or heterotroph.
decomposers such as worms and bacteria in the soil are autotrophs.
decomposers such as worms and bacteria in the soil are heterotrophs.
the grasses represents a heterotroph.
the snail represents an autotroph.
the small bird represents a heterotroph.
the large bird represents a heterotroph.
the grasses represents an autotroph.

Explanation:

• Autotrophs produce their own food (e.g., plants like grasses via photosynthesis).
• Heterotrophs consume other organisms for food. Decomposers (worms, bacteria) break down dead organic matter (heterotrophic as they don't produce own food). Snails, small birds, large birds eat other organisms (heterotrophic).

Answer:

• B. Decomposers such as worms and bacteria in the soil are heterotrophs.
• E. The small bird represents a heterotroph.
• F. The large bird represents a heterotroph.
• G. The grasses represents an autotroph.
