Ecosystem Interactions and Relationships

The video explores various interactions within ecosystems, focusing on mutualism, commensalism, parasitism, and competition. Mutualism benefits both species, as seen with bees and flowers. Commensalism benefits one species without affecting the other, exemplified by remoras and sharks. Parasitism benefits one species at the expense of another, like fleas on dogs. Competition occurs when species vie for the same resources, such as squirrels and mice competing for food and shelter.

What is the primary focus of interactions in an ecosystem?

• The growth of plant life

• The dominance of predators

• The relationships between different species

• The survival of the fittest

In mutualism, how do bees and flowers benefit each other?

• Bees get food, and flowers get water

• Bees get nectar, and flowers get pollinated

• Bees get protection, and flowers get nutrients

• Bees get shelter, and flowers get sunlight

Which of the following best describes commensalism?

• One species benefits, the other is unaffected

• Neither species benefits

• Both species benefit

• One species benefits, the other is harmed

In parasitism, what happens to the host species?

• It remains unaffected

• It suffers due to the parasite

• It benefits from the relationship

• It becomes stronger

What is a common result of competition between species?

• One species dominates the other

• Both species struggle to survive

• Both species thrive

• One species becomes extinct

Which of the following is an example of competition?

• Fleas and dogs

• Bees and flowers

• Squirrels and mice

• Remoras and sharks

How do squirrels and mice compete in their environment?

• By forming mutualistic relationships

• By using the same type of shelter

• By avoiding each other

• By sharing food resources
