Question

The diversity of organisms that share the same community/habitat is called as _____________.

• A. Beta diversity
• B. Gamma diversity
• C. Alpha diversity
• D. Genetic diversity

Answer 1

The Correct Option is C

In the context of ecology and environmental studies, diversity within a specific community or habitat is referred to as Alpha diversity. Alpha diversity measures the variety of species in a given area or ecosystem and is an important metric for understanding the richness and evenness of species within the localized environment. This is distinct from:  

Diversity Type	Description
Beta diversity	Comparison of diversity between ecosystems, indicating the change in species composition from one environment to another.
Gamma diversity	Total diversity of species in a large geographic area that comprises multiple ecosystems.
Genetic diversity	Variability of genetic characteristics within a single species.

Answer 2

The diversity of organisms that shares the same community/habitat is called Alpha diversity.

Additional Context:

• Diversity Types:
  • Alpha (α): Within-habitat diversity (local species richness)
  • Beta (β): Between-habitat diversity (species turnover)
  • Gamma (γ): Regional diversity across multiple habitats
• Measurement Methods:
  • Shannon-Wiener Index (accounts for abundance)
  • Simpson's Diversity Index (weights dominant species)
• Ecological Significance:
  • High alpha diversity indicates ecosystem resilience
  • Tropical rainforests show highest alpha diversity
• Genetic Diversity:
  • Variation within a species' gene pool
  • Measured through allele frequencies

Correct Answer: (3) Alpha diversity.
