Which of the following climate conditions would best support a tropical rain forest ecosystem?

A. dry air and cold temperatures
B. dry air and hot temperatures
C. moist air and cold temperatures
D. moist air and hot temperatures

D. moist air and hot temperatures

The correct answer is D. moist air and hot temperatures.

To determine which of the climate conditions would best support a tropical rainforest ecosystem, we need to understand the characteristics and requirements of a tropical rainforest.

Tropical rainforests are typically found near the equator and have certain key features. They require a combination of warm temperatures, high humidity, and abundant rainfall. Now let's analyze the given options:

A. Dry air and cold temperatures: This climate condition does not align with the requirements of a tropical rainforest. Tropical rainforests need high levels of humidity and cold temperatures are not suitable for the growth of the lush vegetation found in these ecosystems.

B. Dry air and hot temperatures: While hot temperatures are important for tropical rainforests, dry air is not suitable. Rainforests require ample rainfall to sustain the dense plant life.

C. Moist air and cold temperatures: Although moist air exists in this condition, cold temperatures are not conducive to the development of tropical rainforests. The plants and animals found in these ecosystems thrive in warm climates.

D. Moist air and hot temperatures: This option exhibits both the necessary characteristics for a tropical rainforest ecosystem. Moist air provides the required humidity, and hot temperatures are favorable for the growth and survival of the diverse plant and animal species found in tropical rainforests.

Therefore, the climate condition that best supports a tropical rainforest ecosystem is Option D: moist air and hot temperatures.
