B. the fossil record.
Explicación
## Step 1The question is asking us to identify the method by 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 what it was millions of years ago.## Step 3Glacial movement also does not provide evidence of past ecosystems. While it can indicate the climate and geography of the past, it does not provide direct evidence of the existence of a forested ecosystem.## Step 4The fossil record, on the other hand, provides direct evidence of past ecosystems. Fossils are the preserved remains or traces of organisms from the past, and they can provide information about the types of organisms that lived in a particular area, the climate, and the geography. Therefore, by studying the fossil record, scientists can conclude that a forested ecosystem existed in Antarctica millions of years ago.
