Where our food comes from

 Have you ever wonder where all our food comes from 🙋

Who make our food ?

Well! in that case I got you covered. Here we go..

Think about our day to food we eat..Mmm..Rice with some chicken curry ,dhal , fried potatoes and some vegetable salad..sounds delitious right ? Lets look at where these came from..

• Rice - Comes from growing paddy 
• Chicken - There are no chicken plants we can grow..instead they breed chicken in farms..but what does this chicken eat? Different kind of seeds, grains and ground invertebrates such as small worms.
• Dhal - Comes from growing Lentils
• Potatoes - Comes from growing Potatoe plants

By looking at where all these food come from it can be noticed that there is a connection to a plant in every food. Isn't it?

Yes, the answer to the question Where our food comes from? is that they comes from green plants. Even the animal products we eat depends on plants directly or indirectly.

How plants produce food

Green plants use a process called 'Photosynthesis' to produce food. Photosynthesis is a process that take resources (CO2 + H2O) and use sunlight as energy source to produce food in the form of simple carbohydrates (Glucose/ C6H12O6). Then they store simple carbohydrates produced as starch/ sugars in different kinds of fruits they produce.

Role of sun in photosynthesis

We eat food mainly to get energy for our body. If we trace back where all the energy we use comes from it ends with The Sun. 

What happens if photosynthesis stops

As you can imagine we will die with all other organisms in the earth, as we cannot directly utilize energy from The sun.

Is only plants can do photosynthesis 

The answer is No. 

Some other organisms such as,

•  Algae (Diatoms, Phytoplankton, Green Algae)

can utilize light energy from The Sun as well.

Now you know 'Where our food comes from'
