Answer: Enzymes lower the activation energy found in food molecules
Explanation:
Food substances like yam, potatoes, egg etc are all made of chemical elements bounded to one another by chemical bonds such as hydrogen bonds, covalent bonds etc
During digestion, these bonds must be broken for carbohydrates to yield glucose, protein to yield amino acids.
Hence, added enzymes lowers the strength of this bonds i.e activation energy, by placing them into their active sites, which is equipped to cleave specific bonds
Thus, digestive reactions are quicker in the presence of enzymes than otherwise.

Answer:
Sunlight and water.
Explanation:
The sun is the plant's most important nutrient. Plants convert sunlight into sugars in order to grow. Water is needed in two ways, it serves as both a solvent for mineral salts that are carried inside plant cells, and it is an essential component of photosynthesis. The questioner might have asked "name one" so they don't have enough information to answer with any greater certainty - but the answer remains the same regardless of how many nutrients they ask about.
Minerals are also required by plants in order to function properly including calcium, potassium, iron, magnesium just to name a few minerals which are found in healthy nutritious produce!
