This layer exists in the Tropical Rain Forest but not the Temperate Deciduous Forest.

The emergent layer is unique to tropical rainforests

Explanation:

Tropical rainforests are rainforests general found in areas around the world in which there is no dry season. Each month in these regions has an average precipitation of at least 60 mm.

Temperate Deciduous Forest exists in temperate regions.

The major difference between the tropical rain forest and the temperate deciduous forest is the presence of an emergent layer in the tropical rain forest.

The emergent layer of a tropical rain forest is characterized by a small number of very large trees. These trees mostly grow above the height of the general canopy layer.
