Growth stages refer to the distinct phases that an organism or entity undergoes as it develops over time. In biology, these stages typically include embryonic, juvenile, and adult phases, each characterized by specific changes in size, structure, and function. Understanding these stages helps in studying the life cycle of plants, animals, and even humans. In business, growth stages describe the evolution of a company from its inception to maturity. Common stages include startup, growth, expansion, and maturity. Each stage presents unique challenges and opportunities, influencing strategies for funding, marketing, and operations to ensure long-term success.
