What they do for living

What Carbohydrates do for living things.

They are the main source for the body to gain energy.

Simple sugars supply the body with a quick energy source

Complex carbohydrates act as a longer term energy source

What Carbohydrates do for living things.

They are the main source for the body to gain energy.They make up the cell wall in plants which allow them to grow tall, without this carbohydrate, a plant would be a mushy mess! This type of carbohydrate is called Cellulose.

They are the main source for the body to gain energy.They make up the cell wall in plants which allow them to grow tall, without this carbohydrate, a plant would be a mushy mess! This type of carbohydrate is called Cellulose.Animals cannot digest cellulose, therefore it does not provide them with any energy. However, we need to eat it in order for our intestines to work properly, this substance is known as fiber.

What about cows eating grass for energy?

If no animal can get energy from eating cellulose, then why do cows eat grass?

They don’t eat grass, bacteria in their stomachs do. Then the cows digest the bacteria as food!

So it’s like they grow food (bacteria) in their own stomachs!
