Question

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

Answer 1

Answer: option D - Understory

Explanation:

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

Thus, it is a dark place (with low levels of light). And it houses many house plants.

Note that the other options receive ABOVE 15% of sunlight UNLIKE Understory.

So, option D is the right answer
