Changes happen all around us, even within us. Most of them are irreversible but some of them are reversible changes.
A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice.
A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change. When you burn a piece of paper, it turns to ash. It cannot become paper again.

Shadows are formed when light is stopped by an opaque object. An object forms shadow on the opposite side to the source of light. The sunlight also forms shadows of the objects which are on the ground or near the ground. For example – if we stand in the sun, our body casts a shadow on the ground.

Just like us, fishes also need oxygen to survive. However, unlike us they do not have lungs. In case of animals (including human beings), lungs extract oxygen from the air we breathe in and supply it to our blood cells. In case of fishes, breathing air is not possible because they are under water. Fishes consume water and this water is expelled through the gills, but not before dissolved oxygen is extracted from it. The gills are specialized organs and are full of blood vessels. As the water is pushed out of fish's body (through gills), the dissolved oxygen mixes with the blood. And that is how fishes manage to get oxygen while living underwater.
