Multiply and simplify
cot x (sin x + sec x)

Okay. Just to make sure, cot x  = cos x / sin x.

1) So, once cot x is distributed to sin x, then the sin x will cancel out the sin x from the cot x (which I showed you above) and you will be left with just cos x.

2) Once cot x is distributed to sec x (which can be also written as 1 / cos x), the cos x from cot x will cancel out the cos x from sec x.

3) Once you do that, your final answer will be: cos x + (1 / sin x )

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 !
