Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.
On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.
Answer:
B - Python predation has caused a trophic cascade that changed the mosquitoes' niche.
Explanation:
The passage infers that the predation by the Burmese pythons has reduced the population of the animals in Southern Florida thus making the Culex cedecei mosquito to have a reduced number of options to feed from. This is stressed when the author notes that these mosquitoes are now feeding on cotton rats which harbor the Everglades virus that also have the potentials of being transmitted to humans.
Summarily, the passage is saying that the invasion by the Burmese python has changed the niche of most animals including the mosquitoes in the Southern Florida's wild.
There was less of it, making it more possible for the species to be extinct.
<span>If you examine a rock sample and observe fossils in it, the type of rock the sample represent in C - sedimentary. Igneous rock is a melted and cooled rock and there are no remains of any kind of fossils. Still, can be found some fossils traces in some metamorphic rocks with the lowest grade of metamorphism but those are very very rare.
the answer is C, sedimentary </span>
