Exploring Community Interactions and Food Webs

Mrs. Flieg's video tutorial covers community interactions, including competition, predation, and symbiosis. It explains energy flow in ecosystems, trophic levels, and how to construct food chains and webs. The video emphasizes the importance of understanding relationships between organisms and their roles in ecosystems.

What type of competition occurs between members of the same species?

• Interspecific competition

• Mutualistic competition

• Intraspecific competition

• Predatory competition

Which type of competition involves different species competing for resources?

• Mutualistic competition

• Predatory competition

• Interspecific competition

• Intraspecific competition

Which adaptation might a predator use to better catch its prey?

• Hunting in packs

• Producing nectar

• Growing larger leaves

• Warning coloration

What is a key feature of commensalism?

• One organism is harmed, the other benefits

• One organism benefits, the other is unaffected

• Both organisms benefit
