Paragraph on ‘Value of Oxygen and Water in Life/Earth’ in 100 words
Oxygen and water are very important for life on Earth. Oxygen helps us breathe and stay alive. Without it, animals and people cannot live. Water is also needed by all living things. Plants need water to grow, and animals need water to drink. Water keeps our bodies clean and healthy. Oceans, rivers, and lakes are home to many creatures. If we do not have clean water or fresh air, life becomes very hard. We must take care of Earth by keeping the air clean and saving water. This way, all living things can stay healthy and happy.
Paragraph on ‘Value of Oxygen and Water in Life/Earth’ in 150 words
Oxygen and water are the most important things for life on Earth. We breathe in oxygen to stay alive. Without oxygen, we cannot live. Plants give us oxygen through a process called photosynthesis. That is why plants are so important. Water is another key part of life. All living things need water to survive. We drink water to stay healthy. Plants need water to grow and make food. Animals also drink water to live. Water helps keep our Earth cool and clean. Oceans, rivers, and lakes provide homes for many living creatures. Keeping air clean and water pure is very important. Pollution harms the air and water, making it hard for living things to survive. We must not waste water and should plant more trees. By doing this, we can keep Earth a good place for all living things.
Paragraph on ‘Value of Oxygen and Water in Life/Earth’ in 200 words
Oxygen and water are two things that all living beings need to stay alive. Oxygen is a gas that we breathe in every moment. Our bodies need oxygen to make energy. Without oxygen, humans, animals, and even plants cannot survive. Plants play a big role in giving us oxygen. During the day, they take in carbon dioxide and release oxygen. That is why trees and forests are so important for clean air. Water is another essential part of life. We need water to drink, cook, clean, and grow food. Animals also need water to stay healthy. Plants need water to make food through photosynthesis. Water is found in rivers, lakes, oceans, and even underground. It also helps to keep the Earth cool by forming clouds and rain. But, pollution is making our air and water dirty. We must save water and keep the air clean by not wasting natural resources. Planting more trees and reducing pollution will help us protect oxygen and water. Keeping Earth clean means keeping life safe.
Paragraph on ‘Value of Oxygen and Water in Life/Earth’ in 300 words
Oxygen and water are very important for life on Earth. Every living thing needs them to survive. Oxygen is the gas that we breathe in through our lungs. Our body needs oxygen to get energy from food. Without it, we would not be able to live. Plants give us oxygen. They take in carbon dioxide and release oxygen through a process called photosynthesis. This happens mostly during the day when there is sunlight. That is why trees and forests are very important for keeping the air clean and fresh. Water is another essential part of life. Humans, animals, and plants all need water to live. Our body uses water to stay cool, digest food, and remove waste. Plants use water to grow and make food. Without water, crops cannot grow, and we would not have food to eat. Water is found in many places like rivers, lakes, oceans, and underground. It also makes rain, which helps plants and trees grow. But air pollution and water pollution are big problems today. Factories and cars release harmful gases, making the air dirty. Throwing waste in rivers and lakes makes water unsafe to drink. To protect life, we must take care of our air and water. Saving water, planting trees, and stopping pollution will keep Earth healthy.
