Review the list of ecosystem services presented at the end of the lesson. Is biodiversity necessary for ecosystems to supply all of these services? Include statements from the text to support your answer.
Yes. Biodiversity plays a vital role in providing the benefits that are given by the ecosystem for the purpose of maintaining the well-being of humans. It is considered as the foundation of ecosystem services since it is mainly responsible for food production, nutrient cycling, soil formation, biochemical production, carbon storage, water purification, regulation of pests and diseases, pollination of crops, and climate regulation.
Let us take the biodiversity found in the wetlands as an example. Wetlands are considered as productive ecosystems due to its numerous benefits that include supporting diverse life-forms, preventing floods, improving the water quality by filtering waste and pollutants, and providing a source of livelihood for people that live near the area. Without the different life-forms that dwell in the wetlands, its ecosystem would not work efficiently. Without the microbes and plants, nutrient cycling and filtrating of waste and pollutants would not occur. If there are no animals, there would be no balance in the food web and in the entire ecosystem. Without biodiversity, the towns near the coast would have no access to clean water and food. They would have no protection against flooding and coastal erosion.
