Question 1
Which of the following specifically relate to the rain forest biome?
◦ Oxisols
◦ Tropical savanna and steppe climates
◦ seasonal water-balance deficits
◦ precipitation of less than 100 cm, with a summer maximum
◦ average annual temperature of about 25 degrees C (77 degrees F)
Question 2
Why are tropical rain forests the richest terrestrial ecosystems in terms of plant and animal diversity?
◦ Cold is not a limiting factor.
◦ Water is not a limiting factor.
◦ Because of the lack of environmental constraints, many evolutionary varieties can survive and reproduce.
◦ All of these
◦ None of these-the tropical rain forests are not the richest terrestrial ecosystems.
