To select three characteristics that identify a reptile, we need to understand the given options:
1. Cold-blooded: Reptiles are cold-blooded animals, meaning their body temperature depends on the temperature of their surroundings. This is a characteristic that applies to reptiles.
2. Producers: Producers refer to organisms that can produce their own food through processes like photosynthesis. Reptiles do not fall under the category of producers, as they are consumers and obtain their energy by consuming other organisms. Therefore, this characteristic does not apply to reptiles.
3. No backbone: Reptiles, like all vertebrates, possess a backbone or vertebral column, which provides support and structure to their bodies. Therefore, reptiles do have a backbone and this characteristic does not apply to them.
4. Breathe by means of lungs: Reptiles have lungs as their respiratory organs. They breathe air through their lungs, distinguishing them from organisms that have different respiratory systems like gills. This is a characteristic that applies to reptiles.
5. Vertebrates with bony skeletons: Reptiles are vertebrates, meaning they have a backbone or vertebral column. Additionally, their skeletons are made of bones, as opposed to organisms with skeletons made of cartilage. This is a characteristic that applies to reptiles.
From the given options, the three characteristics that identify a reptile are:
- Cold-blooded
- Breathe by means of lungs
- Vertebrates with bony skeletons
