Final answer:
The basic idea in using an ecological model is to look at the inner layers of a problem and work on solutions to those first.
Step-by-step explanation:
The statement is true. Using an ecological model involves examining the different layers of a problem and addressing the innermost layers first. This approach allows for a more comprehensive understanding of the problem and helps in finding appropriate solutions.
For example, if studying a specific ecosystem, starting with the study of individual organisms, then progressing to populations, communities, and ultimately the entire ecosystem would provide valuable insights.
