Question

the power of photosynthesis
photosynthesis is a remarkable process that fuels the growth of plant life on earth. with the help of sunlight, water, and carbon dioxide, plants are able to convert light energy into chemical energy, producing oxygen as a byproduct. photosynthesis is an important example of the many natural processes that drive the world around us. it highlights the essential role that plants play in maintaining the delicate balance of our ecosystem. when sunlight is absorbed by chlorophyll in plant cells, a complex series of chemical reactions is started. carbon dioxide and water are converted into glucose and oxygen. this energy - utilizing process is vital for the growth and development of plants, as glucose serves as a primary source of food and fuel for their survival. the release of oxygen during photosynthesis not only sustains plant life but also plays an important role in maintaining the oxygen levels in the earth’s atmosphere. photosynthesis also contributes to the global carbon cycle by separating carbon dioxide from the atmosphere and storing it in plant tissues. this process combats the effects of climate change by reducing the amount of greenhouse gases in the air. furthermore, the production of glucose through photosynthesis forms the basis of the food chain, providing food and nutrients for humans and other animals, which supports all levels of the ecosystem. if we had been studying the process of photosynthesis, we can gain a deeper appreciation of the way all living organisms work together. plants play a vital role in sustaining life on our planet. photosynthesis demonstrates the power of sunlight in driving the biological processes that shape our natural world and shows the importance of preserving our plant...
which change, if any, is needed to the underlined text?
the atmosphere and stores...
options:

• the atmosphere, and storing it, in plant tissues.
• the atmosphere and storing it in plant tissues.
• the atmosphere and storing it in plant tissues.
• no change

Explanation:

The question seems to be about a sentence related to photosynthesis and the atmosphere. From the text, we know that photosynthesis helps maintain oxygen levels in the atmosphere. The original text says "Photosynthesis not only sustains plant life but also plays an important role in maintaining the oxygen levels in the Earth's atmosphere". The options are about changes to a sentence. Assuming the original sentence part is about the atmosphere and storing (maybe carbon? But the text is about oxygen, but maybe a typo). Wait, the options are about "the atmosphere and stores" or similar. Wait, the text says photosynthesis separates carbon dioxide (from the global carbon cycle part: "Photosynthesis also contributes to the global carbon cycle by separating carbon dioxide from the atmosphere and storing it in plant tissues"). So the correct sentence should be "the atmosphere and storing it in plant tissues" (matching the text). So the correct option is the one with "the atmosphere and storing it in plant tissues".

Answer:

(Assuming the options are as follows, and the correct one is the second option maybe? Wait, the user's image has options:

1. the atmosphere, and storing it, in plant tissues.

1. the atmosphere and storing it in plant tissues.

1. the atmosphere and storing it in plant tissues. (Wait, maybe a typo, but from the text, the correct phrasing is "separating carbon dioxide from the atmosphere and storing it in plant tissues". So the correct option is the one with "the atmosphere and storing it in plant tissues" (probably the second or third option, but let's assume the options are:

A. the atmosphere, and storing it, in plant tissues.

B. the atmosphere and storing it in plant tissues.

C. the atmosphere and storing it in plant tissues. (duplicate)

D. No change.

Then the correct answer is B. the atmosphere and storing it in plant tissues. (Since the original correct phrasing from the text is "separating carbon dioxide from the atmosphere and storing it in plant tissues", so the sentence should have "and storing it in plant tissues" without unnecessary commas.))

B. the atmosphere and storing it in plant tissues
