Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment.

If an animal is an ectotherm, it means that its body temperature is primarily determined by the surrounding environment. Ectotherms rely on external sources of heat to regulate their body temperature. This is in contrast to endotherms, which can generate their own heat internally.
To determine whether an animal is an ectotherm, you can look for certain characteristics:
1. Behavior: Ectotherms often exhibit specific behaviors to regulate their body temperature. For example, they may bask in the sun to absorb heat or seek shade to cool down.
2. Habitat: Ectotherms are commonly found in environments where they can easily access external sources of heat, such as deserts, rocky areas, or sunny habitats.
3. Metabolism: Ectotherms typically have lower metabolic rates compared to endotherms, as they do not need to expend energy on internal heat production.
4. Adaptations: Ectothermic animals may have various adaptations to help them regulate their body temperature. This can include specialized skin or scales, coloration for thermoregulation, or behavioral adaptations like burrowing.
By considering these factors, you can determine if an animal is an ectotherm by examining its behavior, habitat preferences, metabolic characteristics, and specific adaptations.
