Sun as a Natural Resource

Answer

The Sun is a big, hot star made of gases. It gives us light and heat. It is the closest star to Earth and helps all living things survive.

Answer

The Sun gives us light and warmth. Without it, Earth would be dark and very cold. Plants need sunlight to make food, and animals and humans depend on plants for energy.

Answer

Solar energy is the light and heat that the Sun gives to Earth. We can use this energy to cook food, heat water, and make electricity using solar panels.

Answer

Plants use sunlight, water, and air to make their own food in a process called photosynthesis. They use a green substance called chlorophyll to catch sunlight.

Answer

Photosynthesis is the process in which plants make food using sunlight, water, and carbon dioxide. They release oxygen as a by-product.

Answer

Animals eat plants or other animals that eat plants. Since plants need sunlight to grow and make food, all animals indirectly depend on the Sun for energy.

Answer

Plants take in sunlight, water from the soil, and carbon dioxide from the air. Using chlorophyll, they make sugar (food) and release oxygen.

Answer

We can use solar heaters to get hot water, solar cookers to cook food, and solar panels to make electricity for lights and fans.
