Answer :
Sure! Here's a breakdown of whether each of the following living organisms belongs to plankton, nekton, or benthos:
a) Larvas de crustáceos (Crustacean larvae): Plankton - Crustacean larvae are typically part of the plankton community, as they are small and drift along with ocean currents.
b) Erizo de mar (Sea urchin): Benthos - Sea urchins are benthic organisms that live on the seafloor.
c) Atún (Tuna): Nekton - Tuna is a fast-swimming fish that actively moves through the water column, categorizing it as nekton.
d) Alga microscópica (Microscopic algae): Plankton - Microscopic algae fall under plankton since they are tiny and drift with the currents.
e) Lenguado (Flounder): Nekton - Flounder is a fish that swims actively in the water, placing it in the nekton category.
f) Sepia (Cuttlefish): Nekton - Cuttlefish are marine animals that swim actively, making them part of the nekton group.
g) Mejillón (Mussel): Benthos - Mussels are benthic organisms that live attached to surfaces on the seafloor.
h) Tintorera (Blue shark): Nekton - Blue sharks are large, active swimmers, falling into the nekton classification.
Understanding these categories helps us classify marine organisms based on their habitats and modes of movement in the aquatic environment.
