The needs of living things that are met in a space station include:
1. **Air**: Space stations have systems that provide oxygen for astronauts to breathe.
2. **Food and Water**: Space stations are equipped with supplies of food and water to meet the nutritional needs of the astronauts.
3. **Temperature Regulation**: Space stations have systems to regulate temperature since living things require a specific temperature range to survive.
4. **Waste Management**: Space stations have mechanisms to manage waste produced by astronauts.
Regarding whether a space station is an ecosystem, it does not qualify as a natural ecosystem like a forest or a pond. An ecosystem involves living organisms interacting with each other and their physical environment in a balanced way. In contrast, a space station is a human-made structure where the environment is controlled, and the interactions between living things are limited to the astronauts and the provisions provided for them. While it supports human life by meeting their basic needs, it lacks the complexity and diversity of a natural ecosystem.
