The correct answer is option 'A' (i) and (ii) only.
(i) The sun provides green plants with light energy to make food:
- Plants use a process called photosynthesis to make their own food.
- They need sunlight to carry out this process.
- Sunlight provides the energy needed for photosynthesis.
- Without sunlight, plants would not be able to produce food and survive.
- Plants are the primary producers in the food chain, meaning they are the foundation of the entire ecosystem.
- They provide food for animals, including humans, and release oxygen as a byproduct of photosynthesis, which is essential for all living organisms.
(ii) The sun provides heat to enable living things to survive on Earth:
- The sun's energy warms the Earth's surface, creating a suitable environment for life.
- The heat from the sun helps maintain the Earth's temperature within a range that allows living organisms to survive.
- It provides warmth for animals and humans to stay active and maintain their body temperature.
- Sunlight also plays a crucial role in regulating the Earth's climate and weather patterns.
(iii) The statement "It rotates around the Earth to give us seasons" is incorrect:
- The sun does not rotate around the Earth; instead, the Earth orbits around the sun.
- The changing seasons on Earth are caused by the tilt of the Earth's axis as it orbits the sun.
- This tilt causes different parts of the Earth to be exposed to varying amounts of sunlight throughout the year, leading to the different seasons.
In conclusion, the sun is important to the Earth because it provides green plants with light energy for photosynthesis, allowing them to produce food and release oxygen. Additionally, the sun's heat enables living things to survive on Earth by creating a suitable environment and maintaining the Earth's temperature.
