mafiozo [28]

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.

A group of long-billed prairie birds migrates from a pristine, protected prairie to a nearby, newly restored prairie. They colon
spayn [35]

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
