What is the main difference between an endotherm and an ectotherm?
An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
What is a 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.
Which of the following is a characteristic of all Endotherms?
What do all endotherms have? All have a thermostat that regulates body temperature. What body features do endotherms haave to help them stay warm in the cold climates or cool in hot climates? Fat, fur, feathers help endotherms stay warm.
What is the difference between ectotherms and Endotherms Class 12?
Ectotherms are cold-blooded animals. Their temperature differed with their surroundings. Endotherms are warm-blooded animals. They maintain persistent body temperature.
What are the advantages and disadvantages of being an Ectotherm?
They are less active in cooler temperatures and have to warm up in the morning sun before they are more active. This puts them at risk from predators. They are not capable of activity during the winter as they can’t warm up enough. They have to have sufficient stores of energy to survive over winter without eating.
Are Penguins endothermic or ectothermic?
People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles—along with most fishes, amphibians, and invertebrates—are ectotherms. Endotherms generate most of the heat they need internally.
What are the advantages and disadvantages of Ectotherm?
What is one benefit of being a Ectotherm What is one benefit of being a Endotherm?
In general, endothermy is advantageous. One advantage of endothermy is that it gives endothermic animals greater stamina than ectothermic animals. Because of their faster metabolism, endothermic animals can quickly resupply muscles with energy and rapidly break down muscular waste products.
Are endotherms warm-blooded?
endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.
Which two characteristics are shared only by vertebrates?
As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Vertebrates are further differentiated from chordates by their vertebral column, which forms when their notochord develops into the column of bony vertebrae separated by discs.
What is the difference between Aestivation and hibernation?
Hibernation or “winter sleep” is the state of inactivity or low metabolic process performed by the animals during winters. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summers.
Which animals are ectothermic?
Ectotherm, Any so-called cold-blooded animal; that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
What animals are exothermic?
Mammals, birds, and some fish around their eyes and brains are endothermic. Exothermic, what used to be known as cold-blooded animals, are reptiles, amphibians, and fish.
How do ectotherms maintain body temperature?
Ectotherms have no internal heat regulation mechanism like endotherms . Thus, making them heavily reliant on external heat sources to maintain their bodies in a physiologically functioning temperature.
What is an example of an ectotherm?
Examples of ectotherms include reptiles , amphibians , crabs, and fish . Many ectotherms live in environments where very little regulation is needed, like the ocean, because the ambient temperature tends to stay the same. When necessary, crabs and other ocean-dwelling ectotherms will migrate toward preferred temperatures.
