Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
