Question

Tropical rain forests tend to have soils that are nutrient poor, and most of the nutrients are found in the top few inches of the soil.

Which adaptation is most likely found in tropical trees?

deep root systems
shallow root systems
needles
pine cones

Answer 1

shallow root systems

Rationale: In tropical rain forests most nutrients are concentrated in the thin organic layer at the soil surface, so trees typically have shallow, widely spreading roots (and buttress roots) to capture those surface nutrients.
