During a lifetime, a living organism can undergo many changes and a variety of stages. This is known as a “life cycle”. The changes may take different forms, depending on the type of organism in question. In this film, we’ll be taking a look at what a life cycle is. We will also look at several different examples: the life cycles of humans, butterflies, Batrachia and flowering plants. We will explain concepts such as metamorphosis, amphibian and pollination.
