The long term effects of competition on populations of two different species competing for the same source are as follows:
1. It becomes a situation of the survival of the fittest. For example, if two populations of plants compete for the same source, the stronger of the two species will overpower the weaker of the two species. Trees that grow taller will block out the sun and the smaller trees will die. In the animal kingdom, the strongest of the predators that compete for the same prey will survive.
Rainfall is measured as depth on the surface of the Earth, typically in mm. We know the volume of water in the rain gauge: 1414 cubic centimetres. We know need to know the area of the Earth that this volume fell on. This would be the area of the funnel opening that points up to the sky to catch the rain. We know the diameter is 24 cm. So we need to determine the area of a circle with a diameter of 24 cm. The equation to use is: area = pi * radius^2. Since the radius of a circle is half the diameter, the equation is:
So area is <span>3.14159 * 12^2
= 452.39 cm^2
Volume = depth * area
depth = volume/area
depth = </span>1414/452.39
= 3.13 cm = 31.3 mm
The answer is A hope this helped you :)<span />
