150 bottles and 250 bags of trail mix
250 bottles and 150 bags of trail mix
275 bottles and 125 bags of trail mix

please give a step by step explanation!!

250 bottles and 150 bags of trail mix.

Step-by-step explanation:

You multiply 250 times 3.5 and get 875. Then you multiply 150 times 4 and get 600. Then add 875 plus 600 and get 1475.

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 !
