Question

use the scenario to answer the question. a student is examining evidence to support the following claim. "life is possible because of the unique mixture of gases that cycle through the earths spheres." which evidence best supports the students claim? a diagram illustrating how plants use carbon dioxide water and sunlight to produce food and oxygen gas, an illustration demonstrating how the depletion of the ozone layer is not blocking out the suns ultraviolet rays, a photograph capturing a nighttime meteor shower, a timeline detailing when an erupting volcano releases lava ash and gases

Answer 1

A diagram showing how plants use carbon dioxide, water, and sunlight to produce food and oxygen gas.

Why: photosynthesis directly shows gases (CO2 and O2) cycling between the atmosphere and the biosphere and demonstrates how that mixture supports life. The volcano timeline shows gas release but not the ongoing biological cycling that makes life possible.
