2. Explain why photosynthesis is needed for respiration and vice versa. Provide a specific example to support your answer.

Explanation:

Photosynthesis uses carbon dioxide to create oxygen in the atmosphere. Oxygen is what we breathe. We do a process called cellular respiration. This means we breathe in oxygen and breathe out carbon dioxide. Plants use this carbon dioxide to do photosynthesis. It is a never-ending cycle.

For example, a bunny breathes out carbon dioxide. The plant takes carbon dioxide in and gives out oxygen. The bunny breathes in the oxygen and then again breathes out the carbon dioxide.

i think that the best answer would be c.

tell me if im wrong : )

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
