Decay is like watching a banana left on the kitchen counter. At first, it’s yellow and bright, but after a few days, it starts getting brown spots. This is because it’s slowly breaking down and changing. Just like a banana, many things in the world can decay over time, like leaves falling from trees or even old buildings.
Think of a sandcastle you build at the beach. When the tide comes in, the water slowly washes away the sand, and the castle starts to disappear. This is another form of decay, where something that was once strong and tall becomes smaller and eventually vanishes.
Imagine a puzzle that you leave out in the rain. The pieces get soggy and start to fall apart. Decay is similar; it’s when things lose their shape or color over time, like the puzzle pieces getting mushy and not fitting together anymore. This is how nature recycles things, turning them into something new.
