Question

Drag each label to the correct location in the diagram.
Complete the diagram below to show how matter and energy are typically transferred throughout an ecosystem.

Answer 1

I can’t move the labels for you, but here’s exactly where to place each label on the diagram and what arrows to draw:

1. Sun — place above or to the left of the producers. Draw an arrow from Sun to Producers and label it “Energy (sunlight).”
2. Producers (plants/phototrophs) — place at the base of the food chain. Arrow from Producers → Primary consumers.
3. Primary consumers (herbivores) — next trophic level. Arrow from Primary consumers → Secondary consumers.
4. Secondary (and tertiary) consumers (carnivores/omnivores) — place above primary consumers in successive levels (Secondary → Tertiary if shown). Label the arrows between trophic levels “Energy (transferred; much lost as heat).”
5. Heat — place off to the side of the trophic arrows and draw arrows from each trophic level to Heat; label “Energy lost as heat” (shows one‑way energy flow).
6. Decomposers/detritivores (fungi, bacteria, detritus feeders) — place below or to the side of all trophic levels, connected from dead organisms and waste with arrows pointing into Decomposers.
7. Nutrients/Soil (or Matter) — place between Decomposers and Producers. Draw arrow from Decomposers → Nutrients/Soil → Producers and label that loop “Matter/nutrients cycle” (shows recycling).

In short: Sun → Producers → Primary → Secondary → Tertiary (energy flows one-way; energy lost as heat at each transfer). Dead material → Decomposers → Nutrients/Soil → Producers (matter cycles).
