Explanation:
Detailed explanation-1: -Removal of faeces or undigested food from the body is not an example of excretion because undigested food is not a product of metabolism. Metabolic activities generate nitrogenous waste that has to be removed from the body.
Detailed explanation-2: -Removal of undigested food through the anus is not excretion. This process is called defecation.
Detailed explanation-3: -By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished. The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.
