B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
In ecology, a population refers to the group of living organisms of the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce fertile offsprings.
In this question where many sandhill cranes (large flying birds) were observed in their habitat. In addition to the fact that the group of sandhill cranes are found to be living together, they were also observed to be reproducing with other members of the population. This was portrayed by the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation i.e group of sandhill cranes living together and interbreeding, best shows that the observed is a POPULATION of sandhill cranes.
