Answer:

UNA CADENA ALIMENTARIA ES LA RELACON ENTRE LOS MIEMBROS DE UN ECOSISTEMA PARA QUE UNA PARTE DE LA -<u>ENERGIA</u>- SEA TRANSFERIDA ENTRE ELLOS

ExplanatioN:

La cadena trófica es un procesos de tranferencia de energía entre distintos organismos de un ecosistema, en el cual cada organismo en un nivel se alimenta de organismos provenientes del nivel anterior y es comido por organismos del nivel siguiente. Los primeros eslabones de la cadena son autótrofos (fotoautotrofos o quimioautotrofos), productores que sintetizan la materia orgánica a partir de productos inorgánicos.  Los eslabones siguientes son los consumidores heterótrofos: herbívoros, carnívoros, detritívoros.

<u>Paso de energía entre niveles</u>:

Del total de energía que llega a la superficie terrestre, solo el 1% es tomado por los fotoautótrofos. Esta energía adquirida que ingresa a la cadena trófica, tiene un recorrido unidereccional por donde pasa de nivel a nivel, desde los autótrofos hasta los heterótrofos, hasta que finalmente esa energia es disipada nuevamente en el ambiente.

<u>Regla del 10%:</u>

Esta regla establece que solo el 10% de energía utilizada por un nivel trófico pasa al siguiente nivel trófico. Solo el 10% de energía almacenada como biomasa en uno de los niveles tróficos, por unidad de tiempo, se convierte en energia almacenada del siguiente nivel trófico.

Esta progresiva reduccion de energía determina en número de niveles tróficos en esa cadena, que puede ser de cuatro o cinco eslabones.

Are the functions of the limbs of each of the animals illustrated the same or different?
Marat540 [252]
Same

<span>Homologous structures refer to structures that have similar characteristics in terms of morphology, anatomy, genetics, and embryology yet still different when their functions are concerned. On the other hand, analogous structures are those organisms that have similar lifestyle because they live in the same habitat yet they belong in different groups.</span>

Answer:

SIMPLE DIFFUSION transport

Explanation:

According to this question, John could smell the fragrance of his newly bought bottle of cologne all the way up the hall before he can even get into his bedroom, where he usually keeps it. However, he realizes when he got to his bedroom that he left the bottle of cologne uncovered.

The fragrance of the cologne that spreads from the bedroom all through the hall is as a result of SIMPLE DIFFUSION, a form of PASSIVE TRANSPORT. Diffusion is a form of passive transport in which molecules/fluids move from a region of high concentration to a region of low concentration until it is evenly spread. This is the case with John's cologne, which spread from the bedroom where the concentration is high to the hall, where it is low.
