5.

Hotspot: Follow the directions below to answer the question fully. Carefully observe the diagram below and identify how the autotrophs and heterotrophs are identified.

a)

Autotrophs are marked with a star, and heterotrophs with a circle.

b)

Autotrophs are marked with a circle, and heterotrophs with a star.

6.

Choose the best explanation how the autotrophic and heterotrophic classifications of organisms in this woodland scene contribute to the flow of energy within this ecosystem.

a)

Autotrophs produce energy through photosynthesis, while heterotrophs consume other organisms for energy, both contributing to the energy flow in the ecosystem.

b)

Autotrophs consume other organisms for energy, while heterotrophs produce energy through photosynthesis, both contributing to the energy flow in the ecosystem.

c)

Both autotrophs and heterotrophs produce energy through photosynthesis, contributing to the energy flow in the ecosystem.

d)

Neither autotrophs nor heterotrophs contribute to the energy flow in the ecosystem.
