I really need help on this bad

1. The main idea of this passage is about producers and consumers and how they get their food/survive.

2. The difference between producers and consumers is that producers can create their own food through photosynthesis but consumers can't so they eat other organisms to survive. (look at paragraph 2 about producer and paragraph 3 for consumers.

3. Consumers need producers because they generate and release oxygen which is critical for survival it says so in paragraph 4.

4. Cellular respiration results in making energy molecules and ATP essential for survival.

Hope this helps

Explanation:

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.

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.
