The Gruesome Tale of the Hitchhiking Parasite

The video explores the microcosmos, focusing on the interactions between nascla and sectarian. Nascla, a ciliate, lives a colorful life consuming cyanobacteria. However, it becomes a host to the parasitic sectarian, which attaches itself to nascla, using it for transportation and as a food source. The sectarian eventually reproduces by budding while attached to its host. The video concludes by reflecting on the interconnectedness of organisms in the microcosmos and the energy transfer that sustains life.

What is the primary diet of the nascla?

• Fungi

• Algae

• Cyanobacteria

• Plankton

What transformation does the sectarian undergo as it matures?

What happens to the nascla when the sectarian attaches to it?

• It becomes more colorful

• It stops swimming

• It is slowly digested

• It grows larger

How do sectarians reproduce?

• Through binary fission

• By budding

• By laying eggs

• By cloning

What is the final stage of a sectarian's life cycle?

• Becoming a free-swimming organism

• Developing a protective shell
