Exploring Symbiotic Relationships in Nature

The video explains symbiosis, a close relationship between species, highlighting three types: mutualism, commensalism, and parasitism. Mutualism benefits both species, as seen with bees and flowers. Commensalism benefits one species without affecting the other, exemplified by sharks and remora. Parasitism benefits one species at the expense of the other, such as mosquitoes and humans. The video concludes with a summary of these interactions.

What is mutualism?

• A relationship where one species is harmed and the other benefits

• A relationship where both species benefit

• A relationship where one species benefits and the other is unaffected

• A relationship where both species are harmed

What do flowers provide to bees in a mutualistic relationship?

• Water

• Nectar

• Pollen

• Protection

How do bees help flowers in mutualism?

• By providing water

• By providing nutrients

• By pollinating them

• By protecting them from predators

What is commensalism?

• A relationship where one species is harmed and the other benefits

• A relationship where both species are harmed

• A relationship where one species benefits and the other is unaffected

• A relationship where both species benefit

How do remoras benefit from sharks in commensalism?

• By harming the shark

• By getting protection and food scraps

• By feeding on the shark

• By providing cleaning services

What is parasitism?

• A relationship where both species benefit

• A relationship where both species are harmed

• A relationship where one species benefits at the expense of the other

• A relationship where one species is unaffected and the other benefits

How do mosquitoes benefit in their relationship with humans?

• By feeding on human blood

• By getting protection

• By cleaning the environment

• By helping humans

What negative effect do humans experience from mosquitoes in parasitism?

• Loss of nutrients

• None

• Gain of nutrients

• Improved health

What defines a neutralistic relationship?

• One species is harmed, the other benefits

• Both species benefit

• Both species are harmed

• One species benefits, the other is unaffected

Which relationship involves one species benefiting while the other remains unaffected?

• Neutralism

• Parasitism

• Commensalism

• Mutualism
