The source of ecological information I chose is an article from my university library.

b) This source is an academic peer-reviewed research material.
c) The article was written by experts in the environmental sciences field. Each either works at the Environmental Health Laboratory, Department of Environmental Sciences Pakistan, or the Key Laboratory for Heavy Metal Pollution Control and Reutilization, School of Environment and Energy, China. In addition, there are in-text citations across this article as well as a bibliography at the end of the paper.
The source is peer-reviewed because the acknowledgment text states that ” the study was supported by the National Natural Science Foundation of China and the Science and Technology Planning Project of Shenzhen Municipality ”
The source is research material because it contains the “Methods” and “Results” sections stated in the “How to Evaluate Sources of Scientific Information” tutorial from the course materials.
For peer review you need to look for an acknowledgement to anonymous reviewers. Funders do not tell you if it was peer reviewed.
