Biosphere
The biosphere is the part of Earth where life exists, stretching from ocean trenches to the highest points of the atmosphere. It is home to everything from bacteria to whales and towering trees.
Within the biosphere, life thrives in diverse habitats, such as forests, deserts, and wetlands, which provide essential resources for plants, animals, and microorganisms.
The biosphere consists of three key components.
First is the lithosphere. It is Earth’s solid outer layer, including mountains, plains, and ocean floors. It provides habitats for plants, animals, and microorganisms living on land and beneath the soil.
Next is the hydrosphere, which includes all water on Earth, from vast oceans to rivers and lakes. It is essential for aquatic life and supports land organisms that need water to survive.
Then comes the atmosphere, the layer of gases surrounding Earth. It provides oxygen for respiration and carbon dioxide for photosynthesis.
Together, these components create ecosystems where living things interact.
