When would you use a quadrat?
You use a quadrat to isolate a standard unit of area for study of the distribution of an item(s)/organism(s) over a large area.
You use a quadrat to measure the distance between one coral and the next.
You use a quadrat to improve the lighting in dark areas under water.
None of these are uses of a quadrat.
Which of the following is an example of an adaptation that sea otters have?
They can hold their breath for three hours, allowing them to dive down more than a mile.
They have fur that is so dense that, with proper grooming, water doesn’t even touch the skin.
They have special feet that allow them to walk on top of the water.
They don’t have any adaptations that help them survive in the kelp forest ecosystem.
How did the Floral Garden Banks form and get their name?
Created by a now extinct volcano that never broke the surface of the water. They were named by fishermen who would see the bright colors of the reef from their boats.
Created by a fleet of sunken ships from the Civil War that coral started to grow on. They were named by a little girl who saw them when she was swimming next to her dad’s boat.
Created by the uplift of underlying salt domes of Jurassic origin. Named by fishermen who would see the bright colors of the reef from their boats.
None of these are how the Floral Garden Banks were formed or got their name.
