The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, beetle, rabbit, frog, eagle, fox, mountainlion, and fungi.
<h3>What is the trophic web?</h3>The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs- ⇒ herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Example.
To make the trophic web, first, we need to have at least four links.
So first, let us list the organisms we are working with, and then define the position of each of the organisms on the web.
- plants,
- beetle,
- rabbit,
- frog,
- fox,
- mountain lion,
- eagle,
- Fungi
<u>Producer</u> → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.
<u>Consumers</u> → heterotroph
⇒ Herbivores → These are the animals that feed on any part of the plants → These are the beetle and the rabbit
⇒ Carnivores → These are the animals that feed on herbivores → These are the frog, the fox, the eagle, and the mountain lion
<u>Decomposer</u> → detritivorous organisms that take energy from dead matter → Fungi
Trophic web,
- Plants directly provide energy to the beetle and the rabbit
Plant >> Beetle and Rabbit
- The eagle takes energy from the rabbit and the frog takes energy from the beetle.
Rabbit >> Eagle
Beetle >> Frog
- The fox takes energy from the frog and from the rabbit
Frog and rabbit >> Fox
- The Fox and the eagle transmit energy to the mountain lion.
Fox and Eagle >> Mountain lion
- Fungi takes energy from dead organic matter
Plants, beetle, Rabbit, Fox, Eagle, Mountain lion >> Fungi
