Question

Using this list of organisms in the Plankton community answer the following questions. Coscinodiscus, Gonyaulax, Calanoid finmarchus, Nauplius Barnacle, Radiolarian, Megalops Larvae, Foraminiferan, Polychacte, Trochophore Larvae Write each name in the list next to all of the following it applies to: i.e. used more than once Trophic Level 1 Trophic Level 2 Trophic level 3 Herbivore 1^st level carnivore Autotroph Which are Holoplanktonic Which are Meroplanktonic Which are CaCO_3 Which are SiO_2 Which are Cellulose Which are Chiton

Explanation / Answer

Autotroph – Coscinodiscus

CaCO3- Foraminiferan

Herbivore: Foraminiferan, Nauplius barnacle

Trophic level 1: Gonyaulax, polychaete, trochophore larve

Trophic level 2: Calanoid funmarchus, polychaete

Trophic level 3: Radiolarian, polychaete

Haloplankton (They spend their entire life from hatching to death as plankton)– Radiolarian, polychaete

1st level carnivore: Megalops larvae, polychaete

SiO2: Radiolarians have rigid siliceous skeletons

Cellulose: Coscinodiscus argus has shell-like lorica cellulose. Their cells are large at the center with small circumference. It is a variety of Coscinodiscus radiatus and is a fossil.

Chiton: Megalops have exoskeleton made of chiton protein.

Meroplanktonic: Larvae of Nauplius barnacle are meroplanktonic. These larvae are planktonic benthic or nektonic habits.
