Answer:

The common characters shared by frogs and pigeons are:

  • presence of jaws
  • four limbs  

The frogs and pigeons share these characteristics because they both are derived or evolved from a common ancestor.

During the course of evolution, the jaws are evolved in beaks in birds or pigeon as beak is light-weight in comparison to jaws.

Similarly, the forelimbs get covered with feathers to become wings.

Frogs and pigeons both lay eggs. They may both share this characteristic because eggs are an easy way to allow young to develop outside of the womb.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Morgarella [4.7K]

Answer:

tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres

Explanation:

En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.
