Question
How do animals obtain their nutrition?
Solution
The digestive system is different in various animals, so the food and the way nutrition is obtained differ.
In single celled-organisms, like amoeba, the food is taken in by the entire body surface and digested with the heklp of enzymes in the food vacuole. As the complexity in the body of animals increases, different parts specialised to perform different functions like ingestion, digestion, absorption digested food and utilisation.
