What is the difference between endothermic and ectothermic animals?

What is the difference between endothermic and ectothermic animals?

In general, if an organism uses energy to regulate its body temperature internally, then it is considered endothermic. If an organism instead relies on external environmental factors to regulate its body temperature, then it is considered ectothermic.

What is endothermic metabolism?

endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. If heat loss exceeds heat generation, metabolism increases to make up the loss or the animal shivers to raise its body temperature.

What are the advantages and disadvantages of Endothermy and Ectothermy?

Being endothermic allows us to live in cooler areas and regulate our body temperatures to fight off infection (think of the fever you get fighting off the flu). The downside, though, is that regulating body temperature is energetically costly, and warm-blooded animals need more food than cold-blooded ones.

What are the advantages of Ectothermy and Endothermy?

Pros and cons of an endothermic metabolism. The major advantage of endothermy over ectothermy is decreased vulnerability to fluctuations in external temperature. Regardless of location (and hence external temperature), endothermy maintains a constant core temperature for optimum enzyme activity.

How do I compare how endothermic and ectothermic animals respond to changes in environmental temperature?

Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment. Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment.

What is the difference between exothermic and endothermic?

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

What are the advantages of endothermy?

The advantages of endothermy are well known: the ability to occupy thermal niches that exclude many ectothermic vertebrates, a high degree of thermal independence from environmental temperature, high muscular power output and sustained levels of activity, to name but a few.

What do you mean by endothermy?

Endothermy can be defined as any mechanism of heat generation without shivering that increases body temperature and resting metabolic rate.

What is a main advantage of Ectothermy?

Without the need to maintain a body temperature, an ectotherm can use considerably less energy. This means that more energy can be devoted to growth and reproduction per unit of food that the animal obtains.

What are two advantages of Ectothermy?

Advantages

• They use less of their food in respiration.
• They need to find less food and may be able to survive for long periods of time without eating.
• A greater proportion of the energy obtained from food can be used for growth.

What is the main advantage of Ectothermy?

What is one advantage of being an ectotherm? B is correct. Without the need to maintain a body temperature, an ectotherm can use considerably less energy. This means that more energy can be devoted to growth and reproduction per unit of food that the animal obtains.

What is a characteristic of ectothermic animals?

An ectothermic animal, also commonly known as a “cold-blooded” animal, is one who cannot regulate its own body temperature, so its body temperature fluctuates according to its surroundings. The term ectotherm comes from the Greek ektos, meaning outside, and thermos, which means heat.
