Section B: Short Questions

Ans: Ingestion is the first step in nutrition. It is when an animal takes big pieces of food into its body. For example, when you eat a sandwich, you are ingesting food. It is how we start to get the nutrients we need to live.

Q2: How does digestion happen in humans?

Ans: Digestion in humans happens in the stomach and small intestine. First, food is chewed in the mouth, then it goes down the food pipe into the stomach. Here, special juices break down the food into smaller parts so our body can use it.

Q3: What is absorption in nutrition?

Ans: Absorption is the process where our body takes in the nutrients from the food we have eaten. This happens mainly in the small intestine. Tiny finger-like parts called villi help to absorb these nutrients into the blood.

Q4: What is rumination in ruminants?

Ans: Rumination is a special way some animals, like cows, eat their food. They swallow food quickly and then bring it back up to chew it more. This helps them digest tough food like grass better.

Q5: What happens during egestion?

Ans: Egestion is the last step of nutrition. It is when the body gets rid of waste that we cannot use. After the nutrients are absorbed, the leftover, undigested food is turned into faces and comes out of the body through the anus.
