Real easy question can anyone ? how do variables you model real world situations? give an example of a model that uses variables and explain how it people make predictions.

Hello! Well this is actually quite simple. You always have to have more than one variable in order to manipulate or change a certain situation. Two Variables would be the least amount however you could have up to 4 and even more possibly. An example would be how time and speed are related. With these so variables this would be able to make a prediction because it would show the distance a car may be driving. If you only have the distance and the time, this can help you predict the average speed a car might be going. Hope this helped!! :)

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 !
