Humans and ecosystems
Review your understanding of humans and ecosystems in this free article aligned to NGSS standards.
Key points:
- Humans get many benefits from Earth’s ecosystems. These benefits are called ecosystem services.
- There are four types of ecosystem services:
- Provisioning ecosystem services are the resources that people extract from ecosystems. These include foods and drinking water.
- Regulating ecosystem services are all the processes that keep ecosystems healthy. These include fungi decomposing waste and tree roots preventing erosion.
- Supporting ecosystem services are the foundational processes that underlie all life on Earth. These include photosynthesis and the water cycle.
- Cultural ecosystem services are the ways that ecosystems benefit people’s lives and traditions. For example, many people have a religious or cultural connection to an ecosystem. Ecosystems also provide inspiration, fun, and a sense of well-being.
- A loss of biodiversity can make ecosystems less healthy. This can make it harder for people to get the resources and ecosystem services they need.

- what is erosion?(0 votes)
- Erosion, put simply, is when stone or dirt is weathered by wind, water, ice, or foot traffic, and particles of sediment are carried away. For example, a rock in a stream is slowly eroded by the water flow, and eventually becomes smooth. Trees and undergrowth help prevent the erosion of mountains and hillsides.(9 votes)
