What are the 3 stages of life cycle?
In general, the life cycles of plants and animals have three basic stages including a fertilized egg or seed, immature juvenile, and adult. However, some organisms may have more than 3 life cycle stages, and the exact names of each stage can slightly differ depending on the species.
What is a life cycle example?
A life cycle is a series of changes that happens to all living things. Every life cycle is the same for every generation. For instance, a fly’s life cycle begins as a fertilized egg. The egg develops into a fly, which grows until it fertilizes an egg or lays a fertilized egg of its own. The life cycle then begins again with the new fertilized egg.

Why is life a cycle?
A life cycle determines the series of stages that an individual organism passes through from the time it is conceived to the time it produces offspring of its own. This series of stages is called a life cycle since an offspring passes through the same series before they can produce their own offspring.

How to live through the life cycle?
Project 1: Living Through the Life Cycles#N#In this project, students will be introduced to local animals with sets of life cycle sequencing cards. Students will be asked to sort the cards in sequential order of their life cycle stages and then explain why they sorted them the way they did. Next, students will choose a local animal and use various books and technology to research the sequence of the life cycles . Next, they will choose a locomotor movement to represent transitions through the animal’s life cycle. Then, each student in the group will pick a non-locomotor movement as well as a sound to represent a particular stage of the animal's life cycle. Audience members will use observation of rhythm and movement clues to predict which life cycle of the animal the students are performing. Students will explain their reasoning using evidence from the drama along with a writing prompt provided by teacher.
