D. absorption of CO2 from the atmosphere by ocean water
Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.
Answer:
thermophile.
Explanation:
A thermophile is a kind of bacteria that belongs to the Archaea Domain and they are the kind of animals that can live in a region of high or extreme temperature. There has been a research on a kind of thermophile which is known as Methanopyrus kandleri which can exist in an extreme temperature of up to 500° C.
So, if we take a look at the question again we can see that after 48 hours and at 37°C 20,000 bacteria per milliliter are already in the tube and at more higher temperature of 55°C we have 1,568,000 bacteria per milliliter which means that at higher temperature more of the bacterial is produced.
