If my starting energy at the producers is 1500 kcal, using the 10% rule, how much energy is available to the tertiary consumers?

1.5 kcal

Explanation:

The ten (10) percent rule involves how only as low as 10% of the available energy is transferred to each organism in trophic levels. In an ecosystem, the order of trophic levels are: producer ➡ primary consumer ➡ secondary consumer ➡ tertiary consumer.

According to this question, 1500 kcal of energy is starting at the producer level. Hence;

- 10% of 1500 kcal = 10/100 × 1500 = 150 kcal will be available to the primary consumer

- 10% of 150 kcal = 10/100 × 150 = 15 kcal will be available to the secondary consumer.

- 10% of 15 kcal = 10/100 × 15 = 1.5kcal will be available to the tertiary consumer.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
