For this case we have the following expression:
$\frac{9^2}{(-3)^0} 
$
The first thing you should know for this case, is that by power properties we have:
Every number raised to zero is equal to unity.
We then have to rewrite the expression:
$\frac{81}{1}$

The given expression is equal to:

option 4.

Answer from: parkermacyow71bm

Since the expression is not clear, the choices might be - 27 or 81 depending on the expression (see below for detailed explanation)

Justification:

1) If expression to evaluate is 9² ÷ (- 3)

2) In that case, the dividend is: 9² = 81

3) So, the division is 81 ÷ (-3) = - 27.

Remember the law of the signs: the division of opposite signs gives a negative result, while the division of equal signs gives a positive result.

4) If the expression to evaluate is 9² ÷ (- 3)⁰

5) 9² = 81, and (-3)⁰ = 1

6) In this case the division becomes 81 ÷ 1 = 81

Answer from: Quest

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 !
