c

1 and 3 only

d

1, 2 and 3

Answer

Explanation

Equatorial forests (tropical rainforests) exhibit all three characteristics. Statement 1 is correct: the forests have tall, densely packed trees with crowns forming a continuous canopy, creating dense layering. Statement 2 is correct: these forests are biodiversity hotspots with the coexistence of an enormous number of species—they contain more species per unit area than any other terrestrial ecosystem. Statement 3 is correct: epiphytes (plants growing on other plants such as orchids, bromeliads, and lichens) thrive in the humid equatorial environment and are abundant in these forests. All three statements accurately describe the defining characteristics of equatorial forests. > Equatorial rainforests are the planet's most complex ecosystems: dense canopies, maximal biodiversity, and epiphyte gardens creating a vertical city of life. Answer: (d).
