Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb. Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.<span>

No the amount varies for both but there is not an equal amount
Ventricles need more, denser muscular tissue because they pump blood to either the whole body(aorta) or to lungs(pulmonary artery). Atria on the other hand pump blood straight to the ventricles so they do not need as much force and power to pump the blood.
Hope this helps:)
Polymer will reduce only because hydrolysis doesn’t produce but polymer does produce.
