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

7. Why is it impossible for a parent with type AB blood to have a baby with type O blood?
maxonik [38]

Answer: This is because a parent with type AB blood has both A and B antigens therefore, the child must inherit either A or B antigen from the parent.

Explanation: In ABO blood type, blood types are classified on the basis of the antigens present in the red blood cells. There are two types of antigens: A and B antigens.

A blood type is so named because it has A antigens, B blood type has B antigens, AB blood type has both A and B antigens while O blood type has no antigens.

Each of these blood types is controlled by two alleles, and children inherit one allele from each parent. If a parent has AB blood type, none of his offsprings will have O blood type because each offspring must inherit either antigen A or B from this parent.
