Active transport uses up energy while passive transport does not.
The answer is biodiversity.
Coenzymes
Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions.
Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.
Answer: Jet propulsion.
Explanation: A squid uses jet propulsion by filling its muscular mantle cavity (which is used to get oxygenated-water to their gills) with water and then quickly expel the water out of the siphon, just as a "water jet".
I believe that C is the correct answer because Photosynthesizing animals are autotrophs and they can photosynthesize on their own which would make all of the other answers untrue
