How does the bread come to the shop ? Is bread grown on trees? Well bakers bake them in their bakery but
“How do they do it?”
"What do they use?”
Bread essentially is made from the following ingredients :

Flour is derived from wheat which is a crop grown by farmers!

How wheat is cultivated
The wheat is crushed into flour in a Flour Mill. A set of engineers have crafted those very efficient flour grinding equipment. And a set of mill workers using these equipment turn the wheat into flour. Engineering needs a lot of math calculation and measurements !

How flour is manufactured?
How does the flour reach us?
The flour is packed and sent to the market from where we buy it. Again it is the work of a group of mechanical engineers who designed the packing machines and a set of workers who use it to pack and then the storekeeper who sells it to us. Storekeepers need to know their money math really well!

Also we cannot forget that the wheat and the flour is carried from one place to another by huge trucks! It is some automobile engineer who designed and built those trucks and some efficient truck drivers who drive them. Math, science and other skills go hand in hand to make each efficient in their workplace.

Salt is manufactured by salt farmers from rock salt, from seawater and other natural and artificial brines (salty water)

Yeast is a living microorganism that means living things just like us but are way tinier! Where do you think they come from?
What about you? Where did "you" come from? One day we will talk about all this! we will find how life evolved on our planet.
As of now let’s have a look at Yeasts.
Yeast can be grown in factories with the help of yeast cells and molasses from sugarcane juice or other sugar rich products.
Let’s tour a Yeast manufacturing factory.
Since Yeast is a microorganism, the production of Yeast will involve the work of microbiologists, chemical engineers along with mechanical engineers and skilled workers. And can you guess what knowledge they need to have?

Though water is available abundantly in nature yet the water we drink or use for cooking etc is actually purified water / treated water. We might be buying packaged water or have a water filter at home or a RO attached to our kitchen. Even the tap water we use for other purposes is actually treated water.
Whatever be the method of treatment / purification, it's the work of a group of a set of engineers to build the machines, workers to use the machines to process the water, a set of people to help in transporting the water to the market and finally delivered to our homes.
