Question 10

Plants that have large, waxy leaves and shallow root systems and that grow to extreme heights to compete for sunlight are most likely to be found in the tropical rain forest biome.

Tropical rain forests are characterized by their high biodiversity, dense canopy, and the presence of plants with large, waxy leaves that help to reduce water loss. The shallow root systems of these plants allow them to efficiently absorb nutrients from the thin layer of soil before it is washed away by heavy rains.

A) Desert

Deserts are characterized by low rainfall and extreme temperatures. Plants in this biome typically have adaptations such as deep root systems and small, waxy leaves to conserve water, making this option incorrect for the described plant characteristics.

B) Tropical rain forest

This option is correct as tropical rain forests support a wide variety of plant species that have adapted to compete for sunlight. The large, waxy leaves help in minimizing water loss, and the shallow root systems allow these plants to quickly access nutrients in the topsoil.

C) Tundra

The tundra biome features harsh climates with low temperatures and limited vegetation. Plants here are typically low-growing and have adaptations to survive in cold conditions, such as thick leaves or underground storage organs, which do not align with the characteristics described in the question.

D) Savanna grassland

Savanna grasslands are dominated by grasses and have scattered trees. While some trees may adapt to competition for sunlight, they do not typically exhibit the large, waxy leaves and shallow root systems as described, making this option incorrect.

Conclusion

The characteristics described in the question align specifically with the tropical rain forest biome, where plants have evolved large, waxy leaves and shallow roots to thrive in a competitive environment for sunlight and moisture. The other options do not reflect the unique adaptations necessary for survival in such a biodiverse and moisture-rich environment.
