1. Dennis started hiking at sea level. He recorded his starting position as 0. He climbed upward,
and his elevation increased by 400 feet. He recorded his ending position as 400. Using the same
method of measuring, a second hiker had a starting position of -40. Which statement describes
the starting position of the second hiker?

The second hiker started 40 feet below sea level.

Step-by-step explanation:

The second hiker started 40 feet below sea level.

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 !
