Ecological succession is like a story of a forest or a meadow growing and changing over a long time. First, there might be no plants or animals in a new place, but then little plants like moss and grass start growing. These plants help make the soil better, and then larger plants like shrubs and trees can grow too. As the plants change, the animals that live there also change. It’s like a big puzzle where everything fits together to make a beautiful and diverse place.
