Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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?
A
shallow root systems
B
deep root systems
C
pine cones
D
needles
Explanation: 

Detailed explanation-1: -Plants living in tropical rainforests have many unique adaptations. For example, due to the poor nutrient soil, they cannot have deep roots. They withstand many rain events and compete with other plants for sunlight, causing them to sometimes grow at an angle.

Detailed explanation-2: -In the rainforest, most of the carbon and essential nutrients are locked up in the living vegetation, dead wood, and decaying leaves. As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile.

Detailed explanation-3: -Plant adaptations Their leaves and flowers grow in the canopy. Tree trunks-these are tall and thin to allow trees to reach the sunlight. The bark on these trees is smooth to allow water to flow down to the roots easily.

Detailed explanation-4: -In fact, rainforest soils are nutrient-poor because nutrients are not stored in them for very long. The heavy rains that occur in rainforests wash organic material from the soil.
