• B. The trees of temperate forests are taller than those of tropical rain forests.
• C. Giants of temperate forests are comparatively more mesophytic.
• D. Tropical forests are comparatively more homogenous.

Answer 1

Answer: (A)

The tropical rain forests have preponderance of angiosperms while the temperate one have preponderance of gymnosperms.

A tropical rainforest is an ecosystem type, that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the tropic of cancer and tropic of capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. More than two thirds of the world's plant species are found in the tropical rainforests, among which majority are angiosperms.
Temperate forest is in 'Wells Gray Provincial Park' in British Columbia, Canada. Most of them are gymnosperms.
