From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.

---------------------------------------

Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule".

This is, 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 progressive reduction of energy determines the number of trophic levels (4 or 5).

If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.

5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.

1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.

164.5 MJ of this energy is tranferred to the following trophic level.

Which reaction is responsible for the production of lipids when glycerol is joined to three fatty acids?

Anna35 [415]

This reaction is called a condensation reaction. It is also known as a dehydration reaction.

When three fatty acids become attached to a glycerol molecule, a triglyceride is formed. The fatty acids become attached to the glycerol through a condensation reaction named so because 3 water molecules are formed from the 3 OH groups from the fatty acid chains and 3 H atoms from the glycerol.

The bond formed between the fatty acid chain and the glycerol is called an ester linkage.

How do the crystals in a metamorphic rock align if the rock has been exposed to extreme pressure?

Hoochie [10]

Crystals in the metamorphic rock align parallel due to the direction of the applied force, during rock formation. These crystals are Muscovites, Micas, and Amphiboles etc. So, the correct answer to your question is C. And, metamorphic rocks from due to change in texture and mineral assembly, due to the pressure itself.

A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates

kompoz [17]

Answer:

In the cardinals, if the females start using a different criterion than the color of the feather when they choose couple, most likely to happen is that decreased variation in the shades of red because no form of the trait is advantageous.

Explanation:

Options for this question are:

Increased variation in the shades of red because the selection pressure has been relieved.
Increased variation in the shades of red because the cardinals try different ways to impress the females.
Decreased variation in the shades of red because no form of the trait is advantageous.
Decreased variation in the shades of red because the only reason for variation was selection pressure.

In the context of natural selection, male cardinals court females using the coloring of their feathers as a form of sexual selection. This means that the shades of red in the feathers are a selection criterion in these birds, and the more visible shades represent an advantage.

But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate. Instead, the trait that would determine sexual selection would be the one that experiences an increase in its variation.

The difference in an area with high concentration and an area with low concentration is called:.

Musya8 [376]

The difference in an area with high concentration and an area with low concentration is called concentration gradient.

<h3>What is concentration gradient?</h3>

Concentration gradient refers to the difference between the concentrations of two solutes in a solution.

A solution usually contains an area or region with higher concentration and an area with lower concentration.

The difference between these two areas of different concentrations is referred to as a concentration gradient.

wolverine [178]

An electronic pulse oximeter, which can be clipped on the bridge of the nose, forehead, on the earlobe, or to the tip of finger, determines the oxygen concentration in arterial blood. Hemoglobin is the protein complex in blood that is responsible for carrying oxygen around the body. The pulse oximeter actually measures the concentration of hemoglobin in the blood and determines oxygen concentration from this value.
