Answer:
They will experience a decrease in genetic diversity.
Explanation:
This is because one of their genetics has left so the number will decrease.
b. buzzard
c. falcon
d. robin
Answer:
Robin.
Explanation:
Robin is a small bird that are generally found that were earlier classified in the thrush family. These birds generally have orange or red breast. The male and female species are same in color.
These birds are insectivorous and feeds on insects. They have special size beak for eating the insect. The beaks are modified especially for their eating habitats.

Pericardial sac also known as pericardium is a cone-shaped sac made of fibrous tissue surrounding the heart and the blood vessels. It has two parts: the inner coat which is double-layered supporting the heart; and the outer coat which is solid and heavily built attached to the diaphragm and the rear part of the breastbone.
Because ecosystems are densely interwoven spaces with numerous individuals who have complex relationships to one another, many ecological phenomena are challenging to analyze.
When ecological phenomena are arranged into hierarchies, it is frequently possible to create models that simultaneously include impacts from many measurement scales.
This method has been successfully used, for instance, to analyze food webs, where trophic levels correlate to levels in the hierarchy.
Since the temporal dynamics of predators, prey, and herbivores often resolve over comparable amounts of time, measuring the dynamical features of food webs can theoretically be done at the same scale.
Because ecosystems are complex, interconnected systems with numerous players and linkages between them, many ecological phenomena are challenging to analyze.
Therefore, many ecological phenomena difficult to study.
