Which of the following statements about dichotomous keys is true?

• They are used to classify species based on their geographical distribution

• They rely on observable physical features to differentiate between species

• They are only used to identify marine organisms

• They are based on the nutritional requirements of organisms

What is the definition of plankton?

What is the function of a dichotomous key?

• To classify organisms based on their genetic composition
