Ecosystems are communities of living organisms interacting with each other and their physical environment. They can be found in various habitats around the world, including forests, grasslands, deserts, oceans, and wetlands. In this lesson, we will explore the basic concepts of ecosystems, their characteristics, and their importance.

Ecosystems can be found all over the world, from the frozen tundra of the Arctic to the coral reefs of the tropics.

Some of the most significant ecosystems in the world include:

Tropical Rainforest – found near the equator, these forests are characterized by high levels of rainfall and a variety of plant and animal species.

Grassland – found in areas with low rainfall, these vast open plains are home to large grazing animals such as bison, antelope, and zebras.

Desert – found in areas with low precipitation, these arid regions are home to specialized plants and animals that are adapted to survive in extreme conditions.

Importance of Ecosystems

Ecosystems are vital for the survival of life on Earth. They provide us with various ecosystem services, including:

Climate regulation – ecosystems help regulate the Earth’s climate by absorbing and storing carbon dioxide from the atmosphere.

Water purification – ecosystems help filter and clean water, ensuring that it is safe for human consumption.

Biodiversity – ecosystems support a variety of plant and animal species, providing us with food, medicine, and other valuable resources.
