Answer:
Statement (i): Plants do not require water for photosynthesis. (False)
Photosynthesis is the process by which green plants convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. Water is one of the essential components required for photosynthesis. It is absorbed by the roots of plants and transported to the leaves where photosynthesis takes place. Without water, plants cannot carry out photosynthesis effectively, and their growth and development can be hampered.
Statement (ii): About 50% of Earth is covered with water. (False)
Approximately 71% of the Earth's surface is covered with water. This includes oceans, seas, lakes, rivers, and other bodies of water. The remaining 29% consists of landmasses and continents. Water is vital for sustaining life on Earth, playing a crucial role in various ecosystems and supporting diverse forms of life.
Statement (iii): Water should be reused, saved, and conserved. (True)
Water is a finite resource, and its availability is essential for all living organisms. It is crucial to conserve water to ensure its sustainable use and prevent wastage. Conservation of water involves using water efficiently, reducing water usage, and reusing water whenever possible. This helps in preserving water resources, protecting the environment, and ensuring a reliable water supply for future generations.
Statement (iv): Animals that live in water are called aquatic animals. (True)
Animals that live in water are known as aquatic animals. They are adapted to their aquatic habitats and have various adaptations to survive in water, such as streamlined bodies, gills for breathing, and webbed feet for swimming. Examples of aquatic animals include fish, dolphins, turtles, and frogs.
In conclusion, the correct option is 'b) FFTT' as plants do require water for photosynthesis, about 71% of the Earth is covered with water, water should be conserved, and animals that live in water are called aquatic animals.
