Final answer:
Ecosystems provide essential services such as regulating the water cycle, producing oxygen, filtering water, and pollinating crops. These services are important for human survival and have both economic and ecological value.
Step-by-step explanation:
Ecosystems provide a wide range of services to support life on Earth. These services include maintaining the water cycle, producing oxygen, removing greenhouse gases, filtering water, and pollinating crops. For example, forests help regulate the hydrologic cycle by absorbing and releasing water, preventing floods and droughts. Bees, a key species in many ecosystems, provide the important service of pollinating crops, contributing to food production. Overall, ecosystem services are vital for human survival and have both economic and ecological value.
