testAn ecosystem is a community of living organisms and the physical environment in which they exist. Forests, rivers, oceans, wetlands, grasslands, deserts, and even urban green spaces are all examples of ecosystems. Plants, animals, insects, microorganisms, soil, water, and air interact with one another in complex ways. When these relationships remain relatively stable, an ecosystem can continue to function and support life. This condition is often described as ecological balance.
The balance of ecosystems is essential because human beings are also part of nature. We depend on healthy ecosystems for clean air, fresh water, food, fertile soil, medicines, and many other resources. When ecosystems are damaged or severely disrupted, the consequences can eventually affect human health, economies, and quality of life.
