WAEC Agriculture 2011 Paper

Concept:Feed utilization follows the order in which the animal takes in feed, breaks it down, absorbs nutrients, and uses them in the body.Explanation:The correct sequence is $\text{Ingestion} \to \text{Digestion} \to \text{Absorption} \to \text{Assimilation}$Ingestion is the taking in of feed.Digestion is the breaking down of feed into simple nutrients.Absorption is the passage of these nutrients into the blood.Assimilation is the use of the absorbed nutrients by the body cells.Option B starts with ingestion and digestion, so it is the intended answer.However, in Option B the last two terms, assimilation and absorption, are reversed.Answer:Correct sequence: $\text{Ingestion} \to \text{Digestion} \to \text{Absorption} \to \text{Assimilation}$Thus, the intended option is B.
