Did you know that physics underpins everything that happens in Biology? This simple thought may surprise you because biology and physics are very different. But the relationship between these two sciences is important because when we understand physics we can understand biology and vice versa.

Biology is the study of living organisms. Physics is the science of matter and energy. But, how is physics related to biology? What does it mean? The answer is very simple. In physics, we see the relation between matter and energy. It means, we use the energy from food to work and create the energy that we need to live.

It has been seen that the human body has been created with the help of atoms. Atoms have very small parts called electrons and protons. These two elements are used to make different chemicals. They can be used to work.

It has been seen that the process of photosynthesis takes place in leaves. During this process, electrons are used to produce sugars. The electrons are coming from sunlight.

In the whole process, energy comes from sunlight, plants, and animals. In this way, we can say that it is a very simple way. It has been seen that the world has been created from a single particle, which then turned into many particles.

It has been seen that energy can be converted into the form of power and heat. Heat is the form of energy that can be used to do many things. Electricity is one of the things which we can use for doing our work.

So, we can say that energy can be used for many purposes.

However, the main purpose of energy is to sustain the life of plants and animals. It is not meant to destroy the planet.

If we look at the life of a plant, then it can be said that energy is the key to its life.

When you eat something, then you should know that you are eating the energy which is needed for the production of proteins in the human body. It is required to build bones, muscles, and many other tissues.

When you drink water, you are taking in the energy. This energy is used to create the cells which make up your skin and other tissues.

So, we can say that energy is the main component of the body.

As we have mentioned, energy can be used for many purposes. However, the main purpose of energy is to sustain the life of plants and animals. It is not meant to destroy the planet.

We can see the relation between biology and physics. This relation can be used to understand the different subjects. It has been mentioned that the life of plants and animals depends on energy. If we know the relation between biology and physics, then it will help us to understand many things. It will help us to know the real meaning of life.
