Houseplants, which are ideal for indoor decoration because they have adapted to grow in low levels of light, are native to which tropical rain forest layer?
a. lower canopy
b. emergent layer
c. upper canopy
d. understory

option D - Understory

Explanation:

Understory refers to the layer of the rain forest LESS THAN 15% of sunlight.
