Final answer:
Ecosystem services are essential for human well-being and the functioning of the planet. Examples include maintaining the water cycle, providing oxygen, and pollinating crops. There are three types of biodiversity: genetic diversity, species diversity, and ecosystem diversity. Two principles to sustain ecosystems are interdependence and conservation.
Step-by-step explanation:
Ecosystem service refers to the conditions and processes provided by natural ecosystems that are essential for human well-being and the functioning of the planet. Five examples of ecosystem services include maintaining the water cycle, providing oxygen, removing greenhouse gases, filtering water pollutants, and pollinating crops.
Three types of biodiversity are genetic diversity, species diversity, and ecosystem diversity. Genetic diversity refers to the variety of genes within a species, species diversity refers to the number of different species in an area, and ecosystem diversity refers to the variety of ecosystems present in a region.
Two principles to sustain ecosystems are the principle of interdependence, which recognizes that all living organisms are connected and depend on each other, and the principle of conservation, which emphasizes the responsible use and preservation of natural resources.
