The correct answer is '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 can provide information about the climate and geography of a region, but it does not provide direct evidence of past ecosystems. It can indicate whether a region was once covered by ice, but it does not provide information about what types of ecosystems existed there.## 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 what types of organisms lived in a particular region at a particular time. In this case, the fossil record can provide evidence of a forested ecosystem in Antarctica millions of years ago.
