During photosynthesis, plants use( carbon dioxide, nitrogen, or oxygen)obtained from animals.

Photosynthesis is the process by which plants use the energy of sunlight to make sugar (glucose) from carbon dioxide and water. Respiration is the process by which animals use O2 to get energy from food. So plants take in CO2 from the air and produce O2, and animals take in O2 from the air and produce CO2.

Explanation:

your answer would be nitrogen

Explanation:

Like oxygen, nitrogen is essential for living things to survive on Earth. Animals and plants need nitrogen to build amino acids in proteins, which are the building blocks of life. Unlike oxygen, nitrogen cannot be absorbed directly from the air by animals and plants.

i hope this still helps :))

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
