Urgente porfavor ¿Qué características les da a los animales la presencia de un exoesqueleto formado por sales minerales y quitina?

Responder:

Estas son las capas de cobertura más externas de algunos animales -Invertebrados, antropoides, crustáceos. compuesto principalmente por quitina y carbonato de calcio. Son principalmente para proteger los delicados órganos internos de estos animales de los ambientes externos, por lo que ayudan en la conservación del agua y previenen la pérdida de agua.

Explicación:

Otras funciones son.

provisión de soportes de carga

apoyo para el movimiento y la locomoción, porque hay capas de músculos y articulaciones móviles debajo de ellos.

Son impermeables al agua, por lo que evitan el encharcamiento

Explanation:

These are outermost covering layers of some animals -Invertebrates anthropoids, crustaceans. made up of principally  chitin and calcium carbonate. They are principally for protecting the internal delicate organs of these animals from the external environments.Therefore help in water conservation, and prevent water loss.

Explanation:

Other functions are.

provision of weight bearing supports

support  for movement and locomotion,because there are layers of   muscles and movable joint under them.

They are impermeable to water, therefore prevent water logging..

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
