The correct answer is 3 only. Analysis of the StatementsStatement 1 is correct: In high-latitude regions like the Tundra and Taiga of northern Canada, the extreme cold, permafrost, and short growing seasons significantly limit biodiversity. Only a few hardy species (mostly conifers like spruce, fir, and larch) can survive, typically numbering fewer than 12.Statement 2 is correct: The temperate forests of the United States are more diverse than the Taiga but far less diverse than the tropics. In a typical large plot of temperate forest, you will find roughly 30–40 species of trees.Statement 3 is INCORRECT: Tropical forests are the most biodiverse ecosystems on Earth. In Panama, a small area (such as a few hectares) can contain hundreds of different tree species. The statement suggests there are "only 11 species," which is a massive underestimation of tropical biodiversity. For comparison, a single hectare in the Amazon or Panama can have more tree species than the entire United States.
