Amongst the animal groups given below, which one has the highest percentage of endangered species?

Options

A. Insects
B. Mammals
C. Amphibians
D. Reptiles

Explanation

To determine which animal group has the highest percentage of endangered species, we can follow these steps:

### Step 1: Understand the Question
The question asks us to identify which animal group has the highest percentage of endangered species among the options provided.

### Step 2: Review Biodiversity Concepts
Biodiversity refers to the variety of life in a particular habitat or ecosystem. It includes the diversity of species, genetic diversity, and ecosystem diversity. However, biodiversity is not evenly distributed across different taxonomic groups.

### Step 3: Identify the Animal Groups
We need to look at the animal groups mentioned in the options (e.g., amphibians, mammals, reptiles, insects) and understand their respective biodiversity and conservation statuses.

### Step 4: Analyze Endangered Species Data
Research indicates that amphibians are particularly vulnerable to extinction. According to studies:
- Over 32% of amphibian species are currently facing the threat of extinction.
- In comparison, around 23% of mammal species are endangered.
- Reptiles have a lower percentage of endangered species than amphibians.

### Step 5: Compare the Percentages
From the data:
- Amphibians: 32% endangered
- Mammals: 23% endangered
- Reptiles: lower than mammals
- Insects: While they have the highest biodiversity, specific percentages of endangered species are generally lower than amphibians.

### Step 6: Conclusion
Based on the analysis, the animal group with the highest percentage of endangered species is **amphibians**.

### Final Answer: Amphibians
