There is greater biodiversity in tropical /subtropical regions than in the temperate region. Explain.

Answers (1)

Following are the reasons for greater biodiversity in tropical/subtropical regions:

(a) Tropical regions have remained undisturbed during the course of evolution on Earth. However, temperate regions had been subject to frequent glaciations in the past. This provided ample scope for evolution for the organisms in the tropical regions. This could have led to greater biodiversity in the tropical region.

(b) Tropical environment remains more or less constant throughout the year.

(c) More solar energy is available in tropical regions. This helps in higher productivity in this region, which sustains a diverse set of organisms.
