What is the primary layer of the rainforest where most life thrives?

The canopy is recognized as the primary layer of the rainforest where the majority of biodiversity thrives. This layer is formed by the upper branches and leaves of tall trees, which create a dense roof that intercepts sunlight, making it a vibrant habitat for countless species. The canopy not only provides shelter and food sources for many animals such as birds, insects, and mammals but also plays a crucial role in the ecosystem by facilitating processes like photosynthesis.

In contrast, the understory, while still part of the rainforest, is home to fewer species and receives significantly less sunlight, making it less conducive to the abundance of life found in the canopy. Choices like savanna and taiga refer to different ecosystems altogether, characterized by different climates and vegetation types. Savannas are grasslands with sparse trees, while taiga, or boreal forest, consists of coniferous forests in colder climates, neither of which support the same level of biodiversity as the rainforest canopy.
