Answer:
The correct answer is 3 countering the affect of declining CO2 on photosynthesis.
Explanation:
Carbon di oxide is an important reactant of photosynthesis.The atmospheric CO2 label regulates the rate of photosynthesis.
When the label of atmospheric CO2 decrease the photosynthesis rate also declines.
So to countering the effect of declining CO2 on phosynthesis plants increase the number of stomata in their leaves.
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
The answer to this question is Prokaryotes
<u>Complete Question:</u>
Nutria, Myocastor coypus, are large, semi-aquatic rodents native to South America. They were originally introduced in the US in 1889 for their fur. When the nutria fur market collapsed in the 1940's, thousands of nutria were released into the wild by ranchers who could no longer afford to keep them. Characteristics of the nutria include of those here EXCEPT
A. their status changed from introduced to invasive.
B. nutria affect the natural food web of the marshes.
C. nutria inflict permanent damage to marshes and other wetlands
D. nutria can only live in freshwater marshes in coastal areas along the Gulf
Coast.
<u>Correct Option:</u>
The characteristics of the nutria include of those here EXCEPT that "nutria can only live in freshwater marshes in coastal areas along the Gulf Coast".
<u>Option: D</u>
<u>Explanation:</u>
Nutria survives not only in freshwater marshes but also in wetlands, and can respond to various environments reasonably easily. In aquatic habitats, the species flourish and migrate rapidly across rivers into coastal wetlands. Nutria harm prone ecosystems can be seen in many ways.
Beyond destroying plants and crops, nutria kills the channels of ditches, streams, and other water bodies. Even so, the irreversible harm that nutria can do to marshes and other wetlands is of utmost importance. Nutria in these places rely on native plants which hold together wetland soil. This vegetation's degradation exacerbated the depletion of coastal marshes caused by sea level rise.
The oxpeckers are two species of bird which make up the family Buphagidae. Some ornithologists regard them as a subfamily Buphaginae within the starling family, Sturnidae, but they appear to be quite distinct.Oxpeckers are endemic to the savanna of Sub-Saharan Africa. Both the English and scientific names arise from their habit of perching on large mammals (both wild and domesticated) such as cattle, zebras, impalas, hippopotamuses, or rhinoceroses, and eating ticks, small insects, botfly larvae, and other parasites.
According to the more recent studies of Muscicapoidea phylogeny the oxpeckers are an ancient line related to Mimidae (mockingbirds and thrashers) and starlings but not particularly close to either. Considering the known biogeography of these groups, the most plausible explanation seems that the oxpecker lineage originated in Eastern or Southeastern Asia like the other two.This would make the two species of Buphagus something like living fossils, and demonstrates that such remnants of past evolution can possess striking and unique autapomorphic adaptations.
