TED-ED: The microbial jungles all over the place (and you) - Scott Chimileski and Roberto Kolter

The video explores the world of microbes and biofilms, highlighting their formation, benefits, and interactions. Biofilms are complex communities of microbes that provide stability, protection, and opportunities for communication and cooperation. They play a crucial role in ecosystems, contributing to oxygen production, pollution cleanup, and food flavor enhancement. Despite their microscopic size, biofilms have significant impacts on both natural environments and human activities.

What are biofilms primarily composed of?

• Inanimate objects

• Large visible organisms

• Microscopic organisms forming communities

• Single-celled organisms floating independently

How do bacteria initially attach to surfaces to form biofilms?

• By forming spores

• By floating aimlessly

• By using sticky appendages

• By drying up

What is one benefit of microbes living in a biofilm?

• Decreased nutrient availability

• Access to a stable microenvironment

• Increased exposure to predators

• Isolation from other microbes

What is the term used to describe the differentiation of cells into subpopulations within a biofilm?

• Division of labor

• Cellular isolation

• Microbial warfare

• Genetic mutation

How do bacteria compete with each other within biofilms?

• By sharing resources equally

• By secreting chemicals and deploying molecular spears

• By avoiding each other

• By forming alliances

What role do microbes play in the global ecosystem?

• They are insignificant to the ecosystem

• They produce oxygen and help clean up pollution

• They only cause diseases

• They are harmful to all larger organisms

Which of the following foods is enhanced by biofilms?

• Bread

• Cheese

• Rice

• Pasta
