A benign tumour is generally not dangerous as they grow usually within a membrane in one space. They can however grow really big in a short space of time and can cause pressure on neighbouring blood vessels which can be dangerous.

Metastatic or malignant tumours are dangerous and cancerous. After they grow, some cells break off and travel in the bloodstream to a different area of the body (usually the main organs) and forms a secondary tumour there. This keeps happening until the cancer has spread to all of the body.

Energy pyramid: An energy is a graphical model of energy flow of energy community
Andru [333]

1) Each level losses<u> 90% </u>of energy that was contained in the previous level. 2)Protozoa (Producer), snail, shrimp, amphipods (Primary consumers), Salamander (Secondary consumer), Intestinal roundworm (Tertiary consumer), fungi (Decomposer).

<h3>What is the 10% rule in trophic webs?</h3>

The 10% rule states that at each trophic level occurs an energy transference from one of the levels to the next, with only 10% being usable in each of them.

As a general rule, only about 10% of the energy stored as biomass at one trophic level -per unit time- ends up as biomass at the next trophic level -in the same unit of time.

The remaining 90% of energy is lost to the environment as heat.

The progressive reduction of energy determines the number of trophic levels (4 or 5).  

In the xposed example,

1) Each level losses<u> 90% </u>of energy that was contained in the previous level.

2)

  • 1st level: Protozoa ⇒ Producer
  • 2nd level: snail, shrimp, amphipods ⇒ Primary consumer
  • 3rd level: Salamander ⇒ Secondary consumer
  • 4th level: Intestinal roundworm ⇒ Tertiary consumer
  • 5th level: fungi ⇒ Decomposer
