Final answer:
A plankton wheel is a lab device that can be used to periodically and automatically transfer zooplankton between containers. It consists of multiple compartments that rotate and help distribute the zooplankton evenly. The device is commonly used in research laboratories and aquaculture facilities.
Step-by-step explanation:
A lab device that can be used to periodically and automatically transfer zooplankton between containers is called a plankton wheel.
A plankton wheel is a cylindrical device with multiple compartments that rotate at a slow speed, causing the water and zooplankton inside to move from one compartment to another.
This mimics natural water currents and helps distribute the zooplankton evenly in the containers.
This device is commonly used in research laboratories and aquaculture facilities to study and rear zooplankton species, such as copepods or brine shrimp, for various purposes.
The complete question is: What is the lab device that is used to periodically, and automatically transfer zooplankton between containers?
