Flowchart identifying renewable and nonrenewable energy sources with corresponding images and labels.

Let me carefully examine the image to identify each energy source shown and classify them as renewable or nonrenewable.

First, I’ll list all the pictures on the left (under “Renewable”) and right (under “Nonrenewable”), then name each one.

Left side (Renewable):
1. A small green plant sprouting from soil → this is biomass (or plant-based energy), but more specifically, it likely represents bioenergy or just plants used for energy (e.g., wood, crops). In school contexts, this often stands for biomass.
2. Wind turbines → clearly wind energy
3. Sun with solar panels → solar energy
4. A dam with water flowing → hydropower (or hydroelectric energy)
5. A geothermal plant (steam coming from ground, pipes) → geothermal energy

Right side (Nonrenewable):
1. Two barrels (one red, one gray) → these represent oil (petroleum) and possibly natural gas, but barrels usually mean crude oil. Since it's one box, likely just oil.
2. A flame → this symbolizes natural gas (burning gas).
3. A coal cart full of black lumps → coal
4. A nuclear power plant (with cooling towers and radiation symbol) → nuclear energy

Wait — important note: *Nuclear energy is technically not a fossil fuel*, and uranium is finite, so it’s usually classified as nonrenewable in K–12 curricula, even though it’s low-carbon. So yes, in this context, it goes under nonrenewable.

Now let me double-check each:

- Plant → Biomass (renewable)
- Wind turbines → Wind (renewable)
- Sun + solar panel → Solar (renewable)
- Dam → Hydropower (renewable)
- Geothermal plant → Geothermal (renewable)

- Barrels → Oil (nonrenewable)
- Flame → Natural gas (nonrenewable)
- Coal cart → Coal (nonrenewable)
- Nuclear plant → Nuclear (nonrenewable)

All match standard classification for school worksheets.

So the answers to fill in the blanks (left column top to bottom, then right column top to bottom) are:

Renewable (left, 5 items):
1. Biomass
2. Wind
3. Solar
4. Hydropower
5. Geothermal

Nonrenewable (right, 4 items):
1. Oil
2. Natural gas
3. Coal
4. Nuclear

But the worksheet has 5 blank boxes on the left and 4 on the right — matches exactly.

Final Answer:
Biomass, Wind, Solar, Hydropower, Geothermal, Oil, Natural gas, Coal, Nuclear
