Zoology Question 41 – AP-EAMCET 2025

← Back
Find the mismatched pair.

Biodiversity can be measured at different levels, including genetic, species, and ecosystem diversity.

Step 1: Understand the Question✦ Active

The question asks to identify the pair that incorrectly defines a term related to biodiversity.

💡 Teacher's Secret Hint

Familiarize yourself with the different levels of biodiversity measurement.

Step 2: Analyze Alpha Diversity○ Expand

Alpha diversity refers to the diversity of species within a particular habitat or ecosystem. The statement "Alpha diversity - Diversity within a habitat" is a correct definition.

Step 3: Analyze Beta Diversity○ Expand

Beta diversity measures the species diversity between different habitats or ecosystems. The statement "Beta diversity - Diversity between ecosystems" is a correct definition.

Step 4: Analyze Gamma Diversity○ Expand

Gamma diversity refers to the total species diversity across a large region or landscape, which encompasses multiple ecosystems. Diversity at the genetic level is known as genetic diversity. Therefore, the statement "Gamma diversity - Diversity at the genetic level" is an incorrect definition.

💡 Teacher's Secret Hint

Do not confuse gamma diversity with genetic diversity. Genetic diversity is about variation within a species, while gamma diversity is about species diversity across a large geographical area.

Step 5: Analyze Species Richness○ Expand

Species richness is the number of different species present in a given area. The statement "Species richness - Number of species in a given area" is a correct definition.

Step 6: Identify the Mismatched Pair○ Expand

Based on the analysis, the pair "Gamma diversity - Diversity at the genetic level" is the mismatched pair as its definition is incorrect.

💡 Teacher's Secret Hint

Always cross-reference each definition with its corresponding term to ensure accuracy.
