Radiation. Have a nice day.
Almost all the energy in ecosystems comes from the sun.<span>Energy is captured by producers and then passed in a linear progression from one trophic level to the next. At each level, much of the energy escapes the ecosystem as heat. Unlike this one-way flow of energy, matter is recycled within and between ecosystems. Elements pass from one organism to another and among parts of the non-living environment through closed loops called biogeochemical cycles.</span>
There are 5 steps of the scientific method
1. Make a question
2. Do some research for that question.
3. Hypothesis ( guess what might happen during the experiment)
4. Test and Collect Data
5. Conclusion ( what you learned from the experiment)
