Question

The ratio of common and rare species within a given area is different in the Tropical Rainforest than it is in other terrestrial biomes such as the Boreal Forests of New England (NE). Which of the following sets of ratios was suggested in the video for the Tropical Rainforest?
a. 80% common species / 20% rare species,
b. 15% common species / 85% rare species,
c. 50% common species / 50% rare species,
d. 25% common species / 75% rare speciese.
e. 85% common species / 15% rare species.

Answer 1

Answer:

b. 15% common species / 85% rare species.

Explanation:

• As some of the species are more common than other rare species that are strongly dominant and often account for a low species diversity. As the tropical rain forest has a diversity of the species that accounts for 80% of the fort biome as with that of the boreal forest of new England and have low or 10 to 20% of common species.
