How do we get food?
Our primary sources of food are plants and secondary animals.
We get most of our food from plants & animals.
Thus there are two kinds of food,
1. Plant-based food,
From plants, we get food from different parts such as roots, leaves, stems, flowers, and fruits. For example- vegetables, fruits, cereals and pulses, oil, sugar, oil, and spices.
For example- milk, meat, and eggs.
But, there are some sources of food that are not collected from any plants or animals, rather they are invented by humans by mixing different types of chemicals and some exist naturally on Earth.
For example - baking soda, baking powder, vinegar, salt, etc.
We also eat some species of fungi which doesn't belong to any plant or animal kingdom.
For example, the most popular fungi that we eat is 'mushroom'.
