The fertilizers used by farmers can have negative effects on aquatic ecosystems because there is every possibility that the runoffs from the fields can create an algal bloom in the nearby water body. This algal bloom can have a very negative effect on the living organisms of the aquatic body. I hope it helps.
Answer:
The correct answer is "Transgenics".
Explanation:
The missing options of this question are:
A. Artificial selection
B. Transgenics
C. Bioreaction
D. Recombination
The correct answer is option B. "Transgenics"
Transgenics is a term used to describe the artificial insertion of one or more DNA sequences to an organism that would normally not have it. In this example, the term transgenics applies to the cows that serve as hosts for the production of the spider silk. The process transgenics is what gives the name to terms such as "transgenic food", "transgenic plants" or "transgenic animals".

Answer:
While the long-billed prairie-bird’s fundamental niche included a wide range of prey species, competition with other species in the newly colonized prairie reduced the realized niche such that fewer food types were utilized
Explanation:
Options are given:
The two populations of the long-billed prairie-birds had different fundamental niches, but the same realized niche
The original population of long-billed prairie-birds had higher levels of competition for food resources and in order to find enough food had a more varied diet. Those in the newly colonized area faced less competition and adapted to a smaller range of food types.
While the long-billed prairie-bird’s fundamental niche included a wide range of prey species, competition with other species in the newly colonized prairie reduced the realized niche such that fewer food types were utilized
The long-billed prairie-bird’s fundamental niche shifted as a result of competition with other species such that individuals in the newly colonized prairie foraged on a smaller variety of food types
Since in the question it is mentioned that scientists compare the populations with respect to the two bird and determined for the long billed prairie birds and the available of food is same in the two areas
This above situation represents the competitive exclusion concept. The species should be entered into the competitor in the case when there is a large number and the feeding should be started for survival
