Answer to Question 1

D

Answer to Question 2

Each year, an area the size of the state of Wisconsin is deforested in the tropical rainforest (169,000 km2). Because of poor soil fertility in the tropical rain forests, cleared areas are typically abandoned after a couple of years. It then requires between 100 and 250 years for dominant trees to reestablish. Nonetheless, the tropical rain forests (despite their relatively small size) account for 50 of the world's species and approximately 50 of the remaining forest. This loss is a threat to global biodiversity.
