Answer

Explanation

Equatorial forests, also known as tropical rainforests, exhibit all three characteristics. Statement 1 is correct: Equatorial forests are characterized by tall, closely spaced trees whose crown leaves form a dense, continuous canopy that blocks sunlight from reaching the forest floor. Statement 2 is correct: These forests have the highest biodiversity on Earth, with a coexistence of an enormous number of plant and animal species—often thousands of species per hectare. Statement 3 is correct: Epiphytes (plants that grow on other plants without being parasitic) are abundant in equatorial forests, including orchids, bromeliads, and mosses that thrive on the trunks and branches of large trees in the humid environment. All three statements accurately describe the unique characteristics of equatorial forests. > Equatorial Forest Traits: Tall dense canopy, Species-rich biodiversity, Epiphytes abundant due to high humidity and shade. Answer: (d).
