By looking at how the birds interact with fruits in different environment, you can determine where birds are from, what beaks specialize in eating what kind of food, and how those traits came to be (Darwinism)
Answer:
The options are unclear but the answer is 8^2π square feet or 64π sqfeet
Explanation:
Area of a circle is denoted by: πr^2 where r is the radius of the circle.
In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2
= 16/2 = 8 feet.
Thus, the radius = 8 feet.
Hence, Area of a circle = πr^2
= π × 8^2
= 64π or 8^2π sqfeet.
Primary succession occurs when vegetation occurs in a place for the very first time, i.e there was no vegetation there before.
The causes are:
-Erosion
-Physiography
-Elevation
