What is one way an Ectotherm can warm its body?

Shivering helps keep your body warm. This is an example of a metabolic way that endotherms can regulate their body temperature. ... In contrast, ectotherms rely on behavior to regulate their body temperature. They must move their bodies into the shade or sun to cool down or warm up.

What is the reason for the first great amount of adaptive radiation of reptiles?

As the Carboniferous Period came to a close and the Permian Period began, Earth's climate became cooler and less humid. Many lakes and swamps dried up, reducing the available habitat for water- dependent amphibians. Under these drier conditions, the first great adaptive radiation of reptiles began.

Where are the only places on the earth that lack reptiles?

Likewise, permanently aquatic or semiaquatic reptiles are found on all of the continents, except Antarctica and on many smaller land areas where permanent fresh water is present.

How do endotherms warm up?

Endotherms use internally generated heat to maintain body temperature. ... Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment. Animals exchange heat with their environment through radiation, conduction—sometimes aided by convection—and evaporation.

What is the meaning of ectotherms?

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 is adaptive radiation simple?

adaptive radiation, evolution of an animal or plant group into a wide variety of types adapted to specialized modes of life. Adaptive radiations are best exemplified in closely related groups that have evolved in a relatively short time.

What is adaptive radiation in mammals?

During Eocene and Oligocene, most of the orders of mammals originated moving into habitats and ecological niches vacated by the extinct dinosaurs. This evolution from a single ancestral species to a variety of forms which occupy different habitats is called adaptive radiation or divergent evolution.

Which order is correct for the bird digestive system?

The digestive order is as follows: bill, mouth, tongue, pharynx, esophagus, crop, proventriculus, gizzard, small intestine, caeca, rectum, cloaca. shapes and are used for scooping, pecking, tearing and generally picking up the bird's food.

Which choice lists the organs of the bird digestive system in the correct order?

Where is Chyme released?

Chyme or chymus (/kaɪm/; from Greek χυμός khymos, "juice") is the semi-fluid mass of partly digested food that is expelled by a person's stomach, through the pyloric valve, into the duodenum (the beginning of the small intestine).

What are reptiles habitats?

Today, reptiles live in a wide range of habitats. They can be found on every continent except Antarctica. Many turtles live in the ocean, while others live in freshwater or on land. Lizards are all terrestrial, but their habitats may range from deserts to rainforests, and from underground burrows to the tops of trees.

Is it true that Ireland has no snakes?
