Same genus or closely related species.
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.

Two organisms that are related will share the same genus name in their scientific name.

True, they should share fewer homologous structures than two more closely related organisms.

Energy stored from dead organisms can be used in two ways. They can either be eaten by other organisms or decomposed by bacteria with the nutrients absorbed in the soil to be used by plants.
true
The more classification levels two organisms share, the more closely related they are in terms of evolutionary history. Organisms that share many classification levels are likely to be more similar in terms of genetics, anatomy, and behavior.
