Answer 2

Answer:

Digestion begins in the mouth with the secretion of saliva and its digestive enzymes. ... The partially digested food enters the duodenum as a thick semi-liquid chyme. In the small intestine, the larger part of digestion takes place and this is helped by the secretions of bile, pancreatic juice and intestinal juice.

Transport or transportation is the movement of humans, animals and goods from one location to another. In other words the action of transport is defined as a particular movement of an organism or thing from a point A to a Point B. Modes of transport include air, land, water, cable, pipeline and space.

Heterotrophic nutrition is the mode of nutrition in which organisms depend upon other organisms to survive. All animals and non green plants are heterotrophic. Heterotrophic organisms have to acquire and take in all the organic substances they need to survive. ... All heterotrophs depend on autotrophs for their nutrition.
