Joy wants to find the distance, AB, across a creek. She starts at point B and walks along the edge of the river 105ft and marks point C. Then she walks 85ft further and marks point D. She turns 90°and walks until her final location and marks point E. Point E, point A, and point C are collinear.'' 1. Can Joy conclude that ABC and EDC are similar? Why or why not?

2. Suppose DE = 90 ft. Calculate the distance of AB to the nearest tenth of a foot. Show your work.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
