B. The fossil record.
Explicación
## Step 1The question is asking us to identify the method through which scientists can conclude that a forested ecosystem existed in Antarctica millions of years ago. The options provided are: the current climate, the fossil record, and glacial movement.## Step 2The current climate is not a reliable source of information for this question because it does not provide evidence of past ecosystems. The climate can change over time, and the current climate does not necessarily reflect the climate of millions of years ago.## Step 3Glacial movement also does not provide evidence of past ecosystems. While glacial movement can indicate climate change, it does not directly provide evidence of the existence of a forested ecosystem.## Step 4The fossil record, however, can provide evidence of past ecosystems. Fossils are the preserved remains or traces of organisms from the past. By studying fossils, scientists can learn about the types of organisms that lived in a particular area in the past, and thus infer what the ecosystem was like.## Step 5In this case, the fossil record provides evidence of a forested ecosystem in Antarctica millions of years ago. This is because the fossil record contains fossils of trees and other plant species that are known to have lived in forested environments.
