What kind of energy do plants turn solar energy into during photosynthesis?

• Thermal Energy (kinetic)

• Chemical Energy (potential)

• Gravitational Energy (potential)

• Mechanical Energy (moving)

Answer explanation

During photosynthesis, plants take in solar energy and convert it into chemical potential energy. This chemical energy can be used later by the plant for its plant functions. When we eat food, we are using the chemical energy stored in food and turning it back into kinetic energy

What kind of energy is stored in peat?

• Gravitational Energy

• Chemical Energy

• Kinetic Energy

• Thermal Energy

Answer explanation

Energy stored in peat is still chemical energy that was in plants. Remember that plants that don't fully decompose will retain some of their energy.

When plants decompose, decomposers (like bacteria, yeast, and fungi) change energy in the plant matter from Chemical to _____ (choose the best answer)

• Gravitational

• Thermal

• Electric

• Light

Answer explanation

The best answer is thermal, because decomposers will break down plant matter to release its chemical energy. The released energy can be used by the decomposers, and be stored as chemical energy in the decomposer, released as heat, or used for the decomposer to move around (mechanical kinetic)

When most of the matter in the peat formed, the arctic had (More/less/the same) solar radiation hitting it as it has today

• More

• Less

• The Same

Answer explanation

Because there is so much more vegetation stored in peat than can be accounted for from plants growing today, we know much of it must have accumulated during a warm interglacial period (non ice-age), caused by a higher amount of solar radiation hitting the arctic.

During cellular respiration, decomposers (like yeast) break matter from plants into

• Sugar

• Oxygen (O2)

• Carbon Dioxide (CO2)

• Peat

Answer explanation

Cellular Respiration is when decomposers use oxygen to break down sugars in plants and release CO2 and Water

If the earth's northern hemisphere is more angled away from the sun, the arctic will more likely be in an:

• Ice Age (cold period)

• Interglacial Period (Warm period)

• Neither

Answer explanation

The Arctic has warm summers when it is angled towards the sun, which happens every summer. However, the amount the earth angles varies over thousands of years. When the north pole is angled more towards the sun, summers are warmer, so the north isn't in an ice age. When the north pole is angled away from the sun, it gets less solar radiation and will be colder, resulting in an ice age.

When wood burns, what is probably happening to the matter in the wood?

• The matter is fusing into larger molecules (but the wood stays the same mass)

• The matter is breaking down into smaller molecules (but the wood stays the same mass)

• The matter in the wood is turning into CO2 gas (CO2)

• The matter in the wood is turning into O2 gas (oxygen)

Answer explanation

While the wood may also break down into smaller pieces, the primary thing happening during combustion is that solid carbon compounds are being broken down into CO2 and Water. CO2 is released as gas, and water is released as a gas. This is why the mass of our objects decreased when we burned them.
