                          LIFE CYCLE 

A life cycle refers to the series of stages that a living organism goes through during its lifetime, from birth to death. It encompasses the developmental stages and changes that an organism experiences, including growth, reproduction, and eventual decline. The concept of a life cycle is also applied to non-biological entities like products, businesses, and even the economy, highlighting the stages of development, maturity, and decline. 

Biological Life Cycle:

Basic Stages:

Most living organisms, both plants and animals, go through three fundamental stages: a beginning (often as a seed or fertilized egg), an immature juvenile stage, and finally, an adult stage where reproduction occurs. 

Variations:

While these three stages are common, the specific phases and their duration can differ significantly between species. For example, some insects have a larval stage, and some plants have a period of dormancy before germination. 

Examples:

Human life cycles involve stages like infancy, childhood, adolescence, adulthood, and old age. A frog's life cycle includes egg, tadpole, and adult stages. 

Reproduction:

Reproduction is a key part of the life cycle, ensuring the continuation of the species. 

Non-Biological Life Cycles:

Product Life Cycle:

This refers to the stages a product goes through from its introduction to the market to its eventual decline and removal. The typical stages are introduction, growth, maturity, and decline. 

Business Life Cycle:

Similar to the product life cycle, this refers to the stages a business goes through, from its formation to its eventual decline or transformation. 

Information Life Cycle:

This encompasses the stages of information management, including creation, processing, storage, dissemination, and disposal. 

Key Concepts:

Growth: The process of increasing in size and complexity. 

Development: The series of changes an organism undergoes during its lifetime. 

Maturity: The stage where an organism is fully developed and capable of reproduction. 

Decline: The stage where an organism begins to weaken and eventually dies. 

Reproduction: The process of creating new individuals, ensuring the continuation of a species.
