Which of the following statements about tropical rain forests is false?

The statement that tropical rain forests are found on only two continents is inaccurate. In reality, tropical rain forests are present on several continents, including South America, Africa, Asia, and Australia. The Amazon River basin is indeed the largest tropical rain forest, and it is a major example of this ecosystem. Additionally, the biodiversity within tropical rain forests is vast, with more than half of the world’s known plant and animal species residing in these ecosystems. Moreover, tropical rain forests cover less than 10 percent of the Earth's surface, highlighting the limited area they occupy compared to their ecological importance. Thus, the assertion regarding the limited geographical distribution of tropical rain forests is the incorrect statement in this context.
