15 Turn Your Attention To The Pathways Leading To The Gray Whales What Is The Maximum Number Of Trophic Levels You Can Find In Any Pathway Leading To The Gray W class=

Sagot :

The pathway which starts from phytoplankton, crustacean Nauplii, crab larvae and ends with grey whale is the pathway which has maximum number of trophic levels.

What is trophic levels?

The trophic level of an organism is the position that it occupies in a food web or in other words, the trophic level of an organism is the number of steps it is from the start of the chain.

In this graph, the pathway starts from phytoplankton which is eaten by crustacean Nauplii. This crustacean is again eaten by crab larvae and finally by the grey whale. This has maximum number of trophic levels as compared to other pathway.

In a trophic web there are several trophic chains, each with varying number of levels. In the exposed example, the maximum number of trophic levels in the pathways leading to the gray whales is four.

Trophic web

When talking about the trophic web, we refer to the energy transference from one organism to the other.

These organisms place at different levels. Each level feeds on the anterior one and gets eaten by the next one.

The first link is composed of organisms that take radiation energy to produce organic compounds. These are autotroph organisms or producers.

The following links are the consumers:

  • Herbivores are primary consumers and feed on producers.
  • Carnivores are secondary consumers that feed on herbivores.

  • Tertiary consumers feed on secondary consumers, and so on.

The last links are the decomposers, fungi, and microorganisms that act on dead animals degrading organic matter.

Any change that occurs at any of the links will immediately affect the other links too. It will cause an increase or decrease in their population sizes.

In the exposed image of a trophic web, we can identify three trophic chains,

1) From phytoplancton to euphasiids

  From euphasiids to Gray whales

There are three levels:

  • Phytoplancton  ⇒ producer,
  • Euphasiids ⇒ primary consumer,
  • Gray whales ⇒ secondary consumer.

2) From phytoplancton to crustacean Nauplii

   From crustacean Nauplii to Crab larvae

   Fom Crab Larvae to Gray whales.  

There are four levels:

  • Phytoplancton  ⇒ producer,
  • crustacean Nauplii ⇒ primary consumer,
  • Crab larvae ⇒ secondary consumer,
  • Gray whales ⇒ tertiary consumer.

3) From phytoplancton to copepods

   From copepods to Crab larvae

   Fom Crab Larvae to Gray whales.  

There are three levels:

  • Phytoplancton  ⇒ producer,
  • Copepods ⇒ primary consumer,
  • Crab larvae ⇒ secondary consumer,
  • Gray whales ⇒ tertiary consumer.

The maximum number of trophic levels is four.
