The answer is D I'm 100% sure!
When any animal becomes extinct reguardless of its position in the food chain there is a trickling affect to all other links, creating overpopulation and over kill of other species now that the habitat balance has become skewed. Having one species become extinct will cause further issues a for other species down the road.
Answer:
The proportion 'p-hat' that were cyanobacteria is 0.76
Explanation:
The proportion of cyanobacteria is the relationship between the whole sample and the actual quantity of cyanobacteria found in the sample, that were not other algae. In general, proportions are written as fractions. The<em> numerator is the number of cyanobacteria in the sample, while the denominator is the total number of organisms in the sample</em>.
So, in the exposed example we know that
- The sample was composed of 50 algae
- There were two categories for the sample: algae that were cyanobacteria, and algae that were not cyanobacteria
- Algae that were cyanobacteria = 38
- Algae that were not cyanobacteria = 12
If we want to study the relationship between the sample and cyanobacteria and express it as a proportion, then we need to divide the number of cyanobacteria by the number of algae in the sample. This is
38/50 ----> Fraction expression of the relationship between cyanobacteria
and the sample
0.76 ----> Proportion of cyanobacteria in the whole sample.
