What is acceleration?

Biology
2 answers:
Flauer [41]3 years ago

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity, then the object is not accelerating. Basically the changing of speed.

Acceleration, in physics, is the rate of change of velocity of an object. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.

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.

The Florida Panther is the brown and gray species the puma family. For years a small population of the panther lived in the wood
Tasya [4]

The correct answer is - a. It will reduce genetic diversity.

The pumas that live in Florida, also known as the Florida Panthers, will have a much reduced genetic diversity. The reason for this is that the population is very small. It also lives in the same area, where the living conditions are the same. The genetic pool is very small, and the breeding is going on between individuals that have the same traits, and are also relatively closely related, as the mating occurs between the second or third generation that came out form the same parents. That will result in a very reduced genetic diversity, so the Florida Panther will remain the same if the conditions do not change drastically, or these an invasion of pumas from the west into their territory.
