Question

Large unit of land having different types of plants and animals is known as

• A. Uniform vegetation
• B. Biome
• C. Ecosystem
• D. Niche

Answer 1

The correct option is B Biome

Biome is a large regional unit delimited by a specific climatic zone, having a particular major vegetation zone and its associated fauna. For example, tundra desert, temperate deciduous forests etc.

Biome is different from ecosystem. it can be understood as a huge ecosystem or the biggest ecosystem on earth.

Niche is altogether a different concept. Niche is related to ecological role of a species.
