What is number line ?
In which horizontal straight line, we represent integer numbers from low value to high, from left to right, is called number line.
Zero is in the middle of that line.
If we consider the number line, then in the left side of zero, we have all the negative values, where .... < -5< -4< -3< -2< -1< 0
And in the right side of zero, we have all the positive values, where 0<1<2<3<4<5 and so on....
Which animal is closest to sea level ?
We know that, Level zero is called the sea level.
So, if we assume number line in vertical way, then the zero will be the sea level.
Here, if we arrange levels of animals from low to high, we get,
Sea lion(-10)<Shark(-7)<Turtle(-6)<0 <Seagull(+24)
We see that, zero is in between -6 & 24
The distance between 0 & -6 is 6 units whereas between 0 & 24 is 24 units.
So, Turtle is closest to sea level.
