Question

which of the following provides the best evidence that matter cycles and energy flows differently in aerobic versus anaerobic environments?

the rate of water evaporation is faster in open containers than in sealed containers.

earthworms survive longer in soil with air pockets than in waterlogged soil lacking oxygen.

plants grow better in sunlight than in complete darkness.

the temperature of a room changes throughout the day even when the lights stay on.

Explanation:

• Option A: Water evaporation is about physical state change, not matter cycling/energy flow in aerobic/anaerobic contexts.
• Option B: Soil with air pockets is aerobic, waterlogged soil is anaerobic. Earthworms' survival difference shows how matter (nutrients, gases) cycles and energy flows (respiration, metabolism) differ in these environments (aerobic respiration vs. possible anaerobic pathways with less energy efficiency).
• Option C: Compares light vs. dark for plants, not aerobic vs. anaerobic environments.
• Option D: Room temperature change relates to external factors, not aerobic/anaerobic matter/energy dynamics.

Answer:

B. Earthworms survive longer in soil with air pockets than in waterlogged soil lacking oxygen.
