At the base of all food chains, there are green plants and algae. These are called producers and use light energy from the Sun to synthesise their own food through a process known as photosynthesis.

Here are the steps:

1. The process begins when sunlight hits the chlorophyll, a green pigment in the plants and algae that absorbs light energy.

2. This energy is used to combine carbon dioxide from the air and water from the soil to produce glucose, a type of sugar. This process is called carbon fixation.

3. The glucose is then used by the plant for growth and reproduction. Some of it is also stored as starch for later use.

4. Oxygen is released as a by-product of this process. This oxygen is what we and other animals breathe.

5. The energy stored in the plant is then passed on to the next level of the food chain when it is eaten by a herbivore.

This is how green plants and algae, as producers, form the base of all food chains.
