ArbitrLikvidat [17]

Answer:

1.Ratón: se ubica en el segundo nivel trófico, es un consumidor primario que se alimenta de semillas

semillas (productores)---->ratón (consumidor primario)-->serpiente(consumidor secundario) --->zorro(consumidor terciario)

2.

  • Hay 4 niveles tróficos.
  • En el primer nivel se encuentran los productores.
  • En el segundo nivel se encuentran los consumidores primarios, estos se alimentan de los productores.
  • En el tercer nivel se encuentran los consumidores secundarios, los cuales se alimentan de los consumidores primarios
  • En el cuarto nivel se encuentran los consumidores terciarios que se alimentan de los consumidores secundarios.
  • Al consumir lo que se encuentra en el nivel anterior obtienen energía para subsistir y mantener el equilibrio del ecosistema.
  • Los niveles tróficos son los lugares que ocupan un determinado grupo de seres vivos en relación a otros por la energía que tienen y que pasan al siguiente nivel. Se ve en la cadena alimentaria, donde la energía que se obtiene de los nutrientes del nivel anterior siempre es destinada a seres mas grandes en tamaño, es decir que están en el siguiente nivel trófico y necesitan mas energía.

Explanation:

El ratón es un animal herbívoro, es decir que se alimenta de plantas y hierbas, por ende se ubica en el segundo nivel trófico porque consume a los productores. Estos últimos reciben este nombre porque producen su propio alimento a diferencia del resto de los niveles en donde los seres vivos se alimentan de animales o insectos que estén en niveles inferiores.

La energía que obtiene el ratón al consumir a los productores se utiliza en el metabolismo y en las diferentes reacciones que hacen que se mantenga vivo hasta que este es consumido por otro animal transfiriendo la energía al siguiente nivel. Esta cadena sigue hasta llegar al consumidor terciario. En todos los niveles intervienen los descomponedores que degradan los restos de los seres vivos para obtener energía y nutrir la tierra, de esta forma comienzan nuevamente la cadena alimentaria.

A covalent bond is likely to be polar if _____________
Sidana [21]

Answer:

The correct answer d. one of the atoms sharing electrons is much more electronegative.

Explanation:

If one of the atoms is more electronegative than the others, like the oxygen in the water molecule, it will allow this atom to attract the other's electrons turning itself into a negative pole and turning the others into a positive pole. In the water, oxygen is more electronegative and that's why it becomes the negative part and the hydrogens become the positive.

Which element of the scientific process includes the greatest amount of
Stels [109]

Answer:

A living being or organism is a complex set of organizational material, in which molecular communication systems intervene that relate it internally and with the environment in an exchange of matter and energy in an orderly manner, having the ability to perform the basic functions of life that are nutrition, relationship and reproduction, in such a way that living beings work by themselves without losing their structural level until their death.

Explanation:

The matter that composes living beings is formed in 95% by four elements (bioelements) that are carbon, hydrogen, oxygen and nitrogen, from which biomolecules are formed: 3 4

Organic biomolecules or immediate principles: carbohydrates, lipids, proteins and nucleic acids.

Inorganic biomolecules: water, mineral salts and gases.

These molecules are constantly repeated in all living beings, so the origin of life comes from a common ancestor, as it would be very unlikely that two living beings with the same organic molecules have independently appeared.5 6 Stromatolites have been found 3700 million years old, 7 so that life could have arisen on Earth 4100-3800 million years ago.1 8 9

All living things are made up of cells. Inside these are carried out the sequences of chemical reactions, catalyzed by enzymes, necessary for life.

The science that studies living things is biology.
