Lots of factors play different kinds of roles on ecosystems.
Ecosystems are never constant because there are so many levels and layers of animals to each one. It's impossible for the headcount of each species to stay the same within an ecosystem when instances such as flooding, drought, poisoning, and hunting can take part.
Let's say the hawk, who is over the bunny on the pyramid, gets poisoned by water. Now, there's fewer hawks, which means there's less predators to hunt the bunnies, hence causing more bunnies and even increasing the chance of overpopulation.
The animals within ecosystems keep each other in check, but numbers are constantly going up and down as things happen. Natural disasters, pollution, and anything such as, effects the ecosystem, therefore it cannot remain constant.
<h3>The answer to this would be the Archean Eon. </h3>
Answer:
(c) unicellular eukaryotic
Explanation:
Firstly, all prokaryotic cells are unicellular, they cannot be multicellular, so be cannot be correct.
Both Chlamydomonas and Paramoecium are single-celled organisms, so must be unicellular prokaryotic (a) or unicellular eukaryotic (c).
Chlamydomonas and Paramoecium are eukaryotic. They have membrane-bound organelles like a nucleus and food vacuoles. They are examples of protists.
Heterozygous genotype, which is an example of the trait being tall.
To describe the process whereby bacteria on the teeth metabolize carbohydrates producing tooth-damaging acids is used the term tooth (or dental) decay. It is a tooth demineralization process that occurs when a tooth is exposed to an acidic environment of pH 5.5 and below. The primary food source for cariogenic (cavity-causing) bacteria is dietary sugars.Suggestion is to b<span>rush and floss promptly after eating so to insure that dental plaque is not present on your teeth.</span>
