Final answer:
In geography, a map is the term that most closely describes a model. Suggestion is the word closest in meaning to a hypothesis. Analytical modeling is the process of using mathematical equations to model linear aspects of ecosystems.
Step-by-step explanation:
The term that most closely describes a model in geography is D. Map. In geography, a map is a representation of spatial information and is used as a tool to model the real world at a smaller scale. Maps can show physical features, political boundaries, demographic information, and various other data related to geography.
For the second part of the question, the word that is closest to the same meaning as hypothesis would be d. suggestion. A hypothesis is an educated guess or a proposed explanation for a phenomenon, which is a suggestion waiting to be tested.
Regarding the use of mathematical equations in the modeling of linear aspects of ecosystems, the term is a. analytical modeling. Analytical models involve the application of mathematical formulas and equations to analyze and solve problems related to the ecosystem's linear aspects.
