What type of ecosystem is characterized by high precipitation and dense tree cover?

The correct answer is the rainforest. This type of ecosystem is defined by its exceptionally high levels of precipitation, often exceeding 2000 mm (80 inches) annually, which supports a rich diversity of flora and fauna. Rainforests are typically characterized by densely packed trees that create a thick canopy, allowing for a unique microclimate with high humidity and stable temperatures throughout the year.

The lush vegetation in rainforests not only supports numerous species, particularly those adapted to the humid and shaded environment, but also plays a critical role in global carbon cycling and climate regulation. The combination of consistent rainfall and warm temperatures creates ideal conditions for these diverse ecosystems.
