Question 1

[Maximum number: 1]

The mass of an individual organism can affect its physiology and feeding ecology. The diagram shows the relative mass of carbon (black) and total wet mass (grey) of a marine crustacean, Calanus hyperboreus and a jellyfish, Bathocyroe fosteri.

Two crustacean silhouettes representing relative masses: a larger grey outline for wet mass and a smaller black outline for carbon mass.
Two jellyfish silhouettes representing relative masses: a large grey silhouette for wet mass and a small black silhouette for carbon mass. The key identifies the two shadings.

State one process that results in the loss of carbon dioxide from a marine organism such as a crustacean or a jellyfish.
