Trace matter and energy through a food web, then test a population claim
Build an original food-web model, distinguish matter cycling from energy flow, and evaluate invented resource observations using Georgia Grade 7 Life Science references.
Georgia’s current science framework identifies Grade 7 as Life Science. Start with the GaDOE science directory and its adopted Science Georgia Standards of Excellence framework. This activity addresses selected course expectations rather than the entire curriculum.
Explain a grass–insect–bird model without drawing an energy loop
An imagined habitat contains grass, grass-eating insects, insect-eating birds, and decomposers. Air, water, and soil provide nonliving parts of the model. The table gives invented insect counts and leaf availability in two plots. Build a food web, then explain what this small comparison can and cannot show about resources.
| Plot | Available leaves | Insects counted |
|---|---|---|
| A | Fewer | 12 |
| B | More | 23 |
Follow the reasoning
Draw feeding arrows from grass to insects and from insects to birds, defining them as transfers of food matter and stored energy to a consumer. Add pathways from dead organisms and wastes to decomposers. Matter can return to nonliving parts of the ecosystem and be used again. Show sunlight entering separately as energy. Energy transfers through organisms and eventually to the surroundings as heat; it does not cycle back into sunlight through the same food-web arrows. The table shows more insects counted in the plot with more available leaves, but an association alone does not establish its cause.
Check the explanation
A decomposer is not merely the last animal in a feeding chain. Decomposers act on material from several parts of a web, and they also transfer energy to the surroundings. Do not label sunlight as matter or claim that soil minerals return all of an organism’s carbon to a plant. Carbon-containing matter can also move through the air. For the plot comparison, temperature, predators, disease, or counting effort could differ. The supplied observations do not rule those explanations out.
Plan the next activity
- Label living and nonliving components, then define what each kind of arrow represents.
- Trace one matter pathway and one energy pathway aloud; check that the two explanations do not require an energy cycle.
- Compare the resource observations and counts, then identify another observation needed to support the proposed explanation.
Plan repeated observations at the same times with the same counting method. Record leaf availability and other conditions rather than changing the resource and the counting routine together. A larger study might compare several similar plots or use a teacher-designed investigation. Revise the claim when evidence conflicts with it. This model addresses movement of matter and energy without requiring the biochemical mechanisms of photosynthesis or respiration. The selected references belong to Georgia’s Grade 7 Life Science course; other course requirements still need separate study.

How does Grade 7 connect to Georgia science testing?
Grade 7 is outside the Georgia Milestones grade-level science EOG range, which lists Grades 5 and 8. Check the current assessment overview and the school’s course assignments, including any applicable end-of-course assessment. The lessons, practice sets, and books here are independently published resources, not official tests or a certified match to the state assessment. Read the official guidance.
Do the two plots prove that leaf availability caused the insect-count difference?
No. They show a pattern in a small invented comparison. More observations and attention to other conditions are needed to support a causal explanation.
