Consider the following facts:

1. Montane ecology studies life systems on mountains.
2. Dense forests are found at the highest elevations in montane ecosystems.

Which of the above is/are true?

Montane ecology is the branch of ecology that studies life systems on mountains or other high elevation regions on the Earth. The ecosystems on mountains are strongly affected by climate, which gets colder as elevation increases. Dense forests are common at moderate elevations. However, as the elevation increases, the climate becomes harsher, and the plant community transitions to grasslands or tundra.
