Marine Organisms Sampling Methods Quiz

What is the purpose of a line transect in studying marine organisms?

• To place rope along a straight line between two points over an environmental gradient

• To count all species that touch the rope along the entire length

• To estimate populations of sessile marine species

• To collect abundance data using frame quadrats

What is the purpose of a frame quadrat in studying marine organisms?

• To collect abundance data about sessile organisms

• To place rope along a straight line between two points over an environmental gradient

• To estimate populations of motile marine species

• To count all species that touch the rope along the entire length

What is the purpose of a belt transect in studying marine organisms?

• To estimate populations of sessile marine species

• To count all species that touch the rope along the entire length

• To place rope along a straight line between two points over an environmental gradient

• To collect abundance data along an environment gradient

All students may be required to design an experiment. Why is important that their methodology is safe and ethical? Choose two.

• To prevent sunburn and drowning

• To reduce shoreline damage & damage to corals

• To identify potential hazards and reduce the risk of them occurring

• To evaluate and choose ways to protect the natural habitat under investigation
