1. the breaking apart of water in photosynthesis is critical to us as animals because photosynthesis:

produces oxygen.
regenerates rubp.
consumes carbon dioxide.
generates atp.

Explanation:

During photosynthesis, water (\(H_2O\)) is split in the light - dependent reactions. The oxygen (\(O\)) from water is released as \(O_2\) (oxygen gas). Animals, including humans, need oxygen for cellular respiration (the process by which they convert glucose and oxygen into energy, carbon dioxide, and water).
Regenerating RuBP (ribulose - 1,5 - bisphosphate) is part of the Calvin cycle (light - independent reactions) and is more about the continuation of the carbon - fixing process in plants. Consuming carbon dioxide (\(CO_2\)) is also part of the Calvin cycle and is important for plants to build organic molecules (like glucose), but it is not directly related to the benefit for animals from the splitting of water. Generating ATP (adenosine triphosphate) during photosynthesis is used within the plant cells (in the Calvin cycle, for example) for processes like carbon fixation and is not the main direct benefit to animals from the splitting of water.

Answer:

produces oxygen.
