Ecosystem distribution refers to how different types of ecosystems, like forests, deserts, and wetlands, are spread across the Earth. This distribution is influenced by factors such as climate, geography, and human activities. For example, tropical rainforests thrive in warm, humid areas near the equator, while arctic tundras are found in cold regions near the poles. Understanding ecosystem distribution is important for conservation efforts. Different ecosystems support unique species and provide essential services, like clean air and water. By studying where these ecosystems are located, scientists can better protect them and ensure that the planet remains healthy for future generations.
