Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40

First step : Calculate the value of the default population density

Population density = population size (dive 1) / total area

                                                               = 4 / 12  = 0.33

Total area ;

∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²

∴ Total area = 4 + 4 + 4 = 12m².

Final step : Determine the value of the predicted population of brain coral

Population density = ( predicted population ) / predicted area

0.33 = ( pp ) / 120m²

∴ Predicted population ( pp ) = 0.33 * 120

                                                = 39.6 ≈ 40 brain corals

Hence we can conclude that the predicted population of brain coral is 40

Imagine the grasshoppers population was gone. What would happen to the black and white bird population?​
Zina [86]

Answer:

The black and yellow bird population would begin to starve and would be forced to find alternative food, or die off. This would then send ripples through the food web, causing almost every species to be effected by the grasshoppers being gone.
