Suppose the population of a town is 9,800 and is growing 2% each year. a. write an equation to model the population growth. b. predict the population after 7 years. a. y = 9,800 • 1.02x ; about 11,257 people b. y = 9,800 • 2x ; about 11,257 people c. y = 9,800 • 2x ; about 1,254,400 people d. y = 2 • 9,800x ; about 137,200 people

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

Where, a is initial value, r is growth rate and x is time.

The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as

Put x=7 to find the estimated population after 7 years.

Therefore the correct option is A.

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 !
