in which biome is the highest biodiversity found

The biome with the highest biodiversity is the tropical rainforest (tropical evergreen rainforest), especially when talking about life on land.

Quick Scoop

• Tropical rainforests contain more species of plants, animals, fungi, and microorganisms than any other terrestrial biome on Earth.

• They cover only a small fraction of the planet’s land surface (around 6%) but hold roughly about half of all land-based species.

• Warm temperatures year‑round, high rainfall, and a multi‑layered forest structure (canopy, understory, forest floor, emergent layer) create countless niches for different species to evolve and coexist.

If the question is broadened to all biomes on Earth (land plus water), the aquatic biome overall has the most biodiversity because oceans, rivers, lakes, and wetlands together cover about 75% of Earth’s surface and host enormous numbers of known and unknown species.

So, for exams or textbook questions like “in which biome is the highest biodiversity found,” the best single answer is: tropical rainforest biome.
