. Equilibrium: If the number of persons who attend the club meeting this week is X, then the number of people who will attend next week is 80 0.20X. What is a long- run equilibrium attendance for this club

100

Step-by-step explanation:

In economics, for a firm to earn optimum profits, it is important that it achieves a long run equilibrium. We can transfer the same to the case here that for the club to achieve optimum attendance, it must achieve long- run equilibrium attendance.

The condition for Long Run Equilibrium is that:

Club meeting attendance this week = Club meeting attendance next week

X = 80 + 0.20X

X - 0.20X = 80

X = 80/0.8

X = 100.

The long- run equilibrium attendance for this club is 100.

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

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 !
