Morphology
The phrase is a straightforward adjectival modification: 'ancient' (from a long time ago) directly qualifies 'ecosystem' (a community of organisms and their environment), so the combined meaning is easily inferable as an ecosystem from the distant past. This adjective+noun composition is common and cross-linguistically transparent, so a B1 learner who knows both words will readily grasp the MWE's meaning.
Etymology
The phrase ancient ecosystem combines ancient, meaning 'very old', and ecosystem, meaning 'the plants, animals and the place they live'. Imagine layers of soil and fossils that show a whole living place from long ago, so the phrase means 'an environment that existed in the distant past'.
