Answer: Option C - decomposers; they return biotic material to the abiotic component of the Earth

Explanation:

Decomposers are also known as SAPROPHYTES. They feed on and break down dead and decaying remains of plants and animals, thus enabling the release of certain compounds like ammonia, methane gas etc into the environment that then enrich/improve the soil fertility.

Assume that the mother's genotype is AZ/az, and the father's genotype is Az/aZ, and the recombination rate is 10%. What are the
attashe74 [19]

Answer:

0.45 from mom and 0.05 from dad.

Explanation:

The recombinant progeny might occur due to the crossing over at the time of meiosis in which the exchange of chromosomes occur in the homologous chromosomes of non sister chromatids.

The progeny receives half of their chromosome from the mother and half from the father. The mother 50% AZ and 50% az chromosomes respectively. The 10% recombination has occured due to which the mother chromosomes is reduce upto 45%. The recombinant  10% will be aZ and Az and has 5% frequency. Mom has the ability of az chromosomes is 0.45 %. The father has the genotype 50% Az and 50% aZ. The 10% recombination has occured due to which the father chromosomes is reduce upto 45%. The recombinant will be az and AZ with 5% frequency. So, father has az with 0.05 % probability.

Thus, the answer is 0.45 from mom and 0.05 from dad.

1.-La actividad consiste en que identifiques un ser vivo de tu comunidad, ubícalo en alguno de los niveles tróficos y posteriorm
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.
