Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.

Biology
1 answer:
Delicious77 [7]3 years ago
3 0

Answer:

The correct answer is - as energy lost at every trophic level.

Explanation:

In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.

The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
Brilliant_brown [7]

Answer:

(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Explanation:

As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.

Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.

This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.

Two brothers inherit different sets of alleles from their parents. what effect will they have?
lesya692 [45]
Depending on what trait the alleles carry, the brothers will have a different phenotype and a different genotype.
For example; Eye color. My sister is heterozygous, meaning she has brown eyes. I am homozygous recessive, meaning I have blue(green/hazel) eyes. We both have the same parents, I just happened to inherit both of the recessive eye color alleles from my parents whereas, my sister inherited both the dominant and recessive alleles. 

So, since the brothers inherited different sets of alleles, their genotype for a certain trait will be different.

artcher [175]
Within any ecosystem, there is a fixed amount of energy available for organisms to use. since organisms usually produce more offspring than a given ecosystem can support, this causes competition. They compete over who will be the dominant one and who will be left to die.
