The term "Living World" refers to all forms of life on Earth, including plants, animals, fungi, and microorganisms. This diverse array of organisms interacts with each other and their environments, forming complex ecosystems. Each species plays a unique role, contributing to the balance of nature and the health of the planet. In the Living World, organisms are classified into different categories based on their characteristics. For example, plants produce oxygen through photosynthesis, while animals rely on other organisms for food. Understanding these relationships helps scientists study biodiversity and the impact of human activities on ecosystems.
