Biodiversity and Ecosystems

Passage

Biodiversity refers to the variety of life forms in an ecosystem, from plants to animals and microorganisms. Ecosystems, such as forests, wetlands, and coral reefs, support a wide range of biodiversity by providing the necessary conditions for survival. These ecosystems are interdependent, meaning changes in one area can affect the entire system. Biodiversity plays a crucial role in maintaining ecosystem stability and providing essential services such as clean air, water, and food. However, human activities such as deforestation, pollution, and climate change are leading to the loss of biodiversity, which threatens ecosystem balance and can result in the collapse of ecosystems. Protecting biodiversity is essential for sustaining life on Earth.
