What is the first step of nutrition in animals?
Answer and explanation
Correct answer: Ingestion
The governing concept is holozoic nutrition in animals, which occurs through a sequence of ingestion, digestion, absorption, assimilation and egestion. Ingestion means taking food into the body and is therefore the first step. Absorption happens later when digested nutrients enter the blood, while excretion removes metabolic wastes and circulation transports materials. Hence option A is correct.
