an amoeba in a pond engulfs and consumes a paramecium. The amoeba uses which of the following to quickly break down the organic molecules in paramecium O enzymes O glucose O polysaccharides O water

Enzymes

Explanation:

Amoeba uses enzymes to breakdown organic molecules because enzymes are biological catalysts that help to speed up the rate of chemical reaction or breakdown large molecules.

Amoeba have vacuole which fuses to the lysosomes by cytoplasmic movements. The lysosomes are organelles that contain enzymes amylase and proteinase which help to digest carbohydrates and proteins.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
