Detailed explanation-1: -Predators are fewer in number than prey because they are higher up the food chain. In a food chain, an organism passes on only part of the energy it receives from food. With less energy, each level in a food chain supports fewer individuals than the one below it.
Detailed explanation-2: -The main sources for human nutrition include cereals; starchy roots; legumes; vegetables and fruits; sugars, preserves, and syrups; meat, fish, and eggs; milk and milk products; fats and oils; and beverages.
