Step 1: Break Down the Problem

In this question, we are tasked with identifying which of the listed groups are endothermic (warm-blooded) organisms.

Step 2: Relevant Concepts

• Endotherms: Animals that can regulate their body temperature internally, maintaining it independently of the external environment. Examples include mammals and birds.
• Ectotherms: Animals that rely on environmental temperatures to regulate their body temperature. Most reptiles, amphibians, and insects fall into this category.

Step 3: Analysis and Detail

1. Most reptiles: Typically ectothermic.
2. Mammals: Endothermic.
3. Birds: Endothermic.
4. Most amphibians: Generally ectothermic.
5. Insects: Primarily ectothermic.

Step 4: Verify and Summarize

Based on biological classifications:

• Endotherms identified:
  • Mammals
  • Birds

Final Answer

The endotherms from the given options are: mammals and birds.
