Question

Read the context and choose the option with the correct sequence. The food is taken in, biochemically broken down, which is absorbed and circulated to all the cells. Thus the sequence in nutrient acquisition is -

• A. Assimilation, digestion, absorption, ingestion, egestion
• B. Digestion, assimilation, absorption, ingestion, egestion
• C. Ingestion, digestion, absorption, assimilation, egestion
• D. Absorption, assimilation, ingestion, digestion, egestion

Answer 1

The correct option is C

Ingestion, digestion, absorption, assimilation, egestion

The food is first ingested i.e., taken in, then digested, and the digested food is absorbed and then assimilated, i.e., transported and used to perform various functions. Finally the egestion or excretion of undigested or unwanted food is carried out. Hence,

Ingestion $\Rightarrow$ Digestion $\Rightarrow$ Absorption $\Rightarrow$ Assimilation $\Rightarrow$ Egestion.
