Invasive species in time destory biodiversity of an ecosystems

Explanation:

So lets go over what each answer is:

Invasive species are species that invade a ecosystem, and can harm other species and take over resources.

Populatiuons are what make up an ecosystem. There are many populations in a single ecosystem.

Biotic factors are the living things found in the world.

Abiotic factors are the opposite, being the nonliving things found in the world.

Looking at these, which would eventually destroy the biodiversity(variation of species) of an ecosystem?

This would be invasive species, for it is the only answer that harms it's ecosystem.

And this is correct, for invasive species often times can cause extiction of species, or even whole ecosystems.

For example of an invasive species, if a tree-consuming and widly reporudcing insect that lives in plains, invades a pine forest, it will eventually kill off all the trees in the area.

This wont only kill off the pine trees, but harms and could potentiallu kill the species that depend on the pine trees for survival.

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.
