How is solar system made useful to the living world? (Class 10) (give me a proper answer please)
Answers
Solar energy (sunlight) is crucial for our survival on Earth. Sunlight (visible light) falls on the leaves of plants where a process called photosynthesis takes place. The energy (red and blue light) that plants absorb from the Sun is the energy supply for the building of simple sugars that are then converted into starch for storage. The plant can then use this energy store to grow. When we eat plants, the stored chemical energy from the plant is transferred to us. This provides us with an energy store for all our life processes such as growing, moving, making sounds and breathing. All life is dependent on the Sun’s energy
Electricity
Just as solar energy is transformed to a useful form of energy in plants and animals (through the food chain), scientists have discovered that we can also convert solar energy into electrical energy (electricity) for our needs.
There are at least 2 ways currently used for converting solar energy into electricity
Solar (photovoltaic) cells are used to convert solar light energy into electricity.
Concentrating solar power (CSP) allows a large area of sunlight to hit a trough where solar collectors (lenses, mirrors and tracking systems) concentrate it into a beam that boils liquid in order to make steam, which moves turbines to make electricity.
