Water animals like fish have fins and gills for swimming and breathing underwater. Frogs and water birds have webbed feet. Land animals walk and breathe air through lungs. Aquatic plants float or have roots in water beds, like lotus or reeds. In contrast, land plants are rooted firmly in soil. These differences show how water and land creatures adapt to survive in their respective habitats.

When a drop of water is placed on plain paper, it spreads out and gets absorbed. But on wax crayon-colored paper, the water drop stays on top and doesn't spread.

When a drop of water is placed on plain paper, it spreads out and gets absorbed. But on wax crayon-colored paper, the water drop stays on top and doesn’t spread. This shows how wax makes surfaces waterproof. Similarly, plant leaves often have a waxy layer that prevents extra water from entering, protecting them from damage and keeping them healthy by avoiding waterlogging.

If fish disappear, it will disrupt the food chain in water ecosystems. Birds, frogs, snakes and other animals that depend on fish for food will face starvation. This can lead to their extinction too. Humans who rely on fishing for food and livelihood will be affected. Such imbalance weakens the ecosystem, reduces biodiversity and makes the environment unstable for other aquatic life forms as well.

Ocean water is salty and cannot be used directly for drinking or farming. Snow is water in its solid state, seen in cold regions. Steam is water in gaseous form produced when water is heated. Rainwater is freshwater and usable for drinking, farming and daily needs. These forms show how water exists in nature in different states—solid, liquid and gas—and has varying uses and availability.

The majority of Earth’s water is in the oceans and is too salty for drinking or farming. Only a small portion is freshwater and much of it is locked in glaciers or deep underground. The available freshwater in rivers, lakes and underground sources is limited. Because desalinating ocean water is costly, we mostly depend on these small freshwater sources for drinking, farming and everyday use.
