The correct answer is (c), tropical rain forests.
Tundra is a cold, treeless plain found in the Arctic and Antarctic. Coniferous forests are forests dominated by cone-bearing trees, such as pines, firs, and spruces. Temperate forests are forests found in temperate climates, which are characterized by warm summers and cool winters.
Tropical rain forests are the most biodiverse ecosystems on Earth. They are home to more than half of the world’s plant and animal species. Tropical rain forests are also important for regulating the Earth’s climate.
Here are some reasons why tropical rain forests are so biodiverse:
- They have a warm, wet climate that is ideal for plant growth.
- They have a long history of evolution, which has allowed many different species to develop.
- They are home to a wide variety of habitats, including forests, swamps, and grasslands.
- They are located near the equator, which receives more sunlight than other parts of the world.
Tropical rain forests are facing many threats, including deforestation, climate change, and pollution. These threats are causing the loss of biodiversity and the destruction of these important ecosystems. It is important to protect tropical rain forests so that they can continue to provide us with the many benefits that they offer.
