Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions
Ecosystems are the intricate web of life on Earth, encompassing living organisms, their physical environment, and the complex interactions that sustain life. From lush rainforests to vast oceans, every ecosystem plays a critical role in maintaining the delicate balance of our planet's biodiversity and supporting the well-being of all living beings.
Ecosystems are hotspots of biodiversity, housing a vast array of plant and animal species. The interdependence among different species in an ecosystem ensures a harmonious coexistence, where each organism plays a unique role in the ecosystem’s functionality. Not only does biodiversity contribute to the beauty of nature, but it also serves as a genetic reservoir for potential medicines, food sources, and solutions to environmental challenges.
Ecosystems are vital in regulating the Earth's climate. Forests, for instance, act as carbon sinks, absorbing and storing carbon dioxide from the atmosphere, mitigating the greenhouse effect, and helping combat global warming. Oceans play a significant role in absorbing excess heat and carbon dioxide, regulating weather patterns and stabilizing temperatures. Wetlands, marshes, and other aquatic ecosystems act as natural water purifiers. They filter pollutants, excess nutrients, and sediment from water, enhancing water quality. Additionally, forests and vegetation in terrestrial ecosystems help maintain water balance by reducing runoff and preventing soil erosion, which contributes to maintaining the health of freshwater sources and aquifers.
Also, ecosystems provide numerous economic benefits to human societies. Industries such as agriculture, fishing, forestry, and tourism heavily rely on healthy ecosystems. Natural resources obtained from ecosystems, including timber, fuel, and minerals, contribute to the global economy. Conserving ecosystems is not only an ethical responsibility but also a smart economic investment for future generations.
