How is the sun ultimate energy source for food?

1. Sunlight provides energy in the form of photons.

2. Plants capture this light energy using chlorophyll, a green pigment found in their leaves.

3. Photosynthesis converts light energy, water, and carbon dioxide into glucose (a type of sugar) and oxygen. This glucose is the plant's food source, providing energy for growth and other functions.

4. Animals eat plants or other animals that have eaten plants, obtaining the glucose (and energy) stored within them.

5. Humans are also consumers, getting our energy by eating plants and animals.

Kortfattet:

* Sunlight is the primary source of energy for Earth.

* Plants convert sunlight into chemical energy (glucose) through photosynthesis.

* Animals get their energy by consuming plants or other animals that have eaten plants.

* Humans are part of this food chain, relying on plants and animals for our energy.

Therefore, the sun, through photosynthesis, is the ultimate source of energy for all food we consume.
