UNA CADENA ALIMENTARIA ES LA RELACON ENTRE LOS MIEMBROS DE UN ECOSISTEMA PARA QUE UNA PARTE DE LA ---------------SEA TRANSFERIDA
oksano4ka [1.4K]

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.
