Symbiotic Relationships

How can symbiotic relationships affect evolution?

• They can lead to co-evolution, where species adapt in response to each other.

• They have no impact on evolutionary processes.

• They only affect the physical traits of a species.

• They cause species to become extinct more rapidly.

What is the difference between mutualism and commensalism?

• In mutualism, both organisms benefit; in commensalism, one benefits and the other is unharmed.

• In mutualism, one organism benefits while the other is harmed; in commensalism, both organisms benefit.

• In mutualism, both organisms are harmed; in commensalism, one benefits and the other is unaffected.

• In mutualism, one organism is unaffected; in commensalism, both organisms benefit.

What is the role of competition in ecosystems?

• It helps regulate populations and resource use among species.

• It promotes biodiversity by allowing all species to thrive equally.

• It leads to the extinction of weaker species only.

• It has no significant impact on ecosystem dynamics.

What is mutualism?

• A relationship between two organisms in which both organisms benefit.

• A relationship where one organism benefits at the expense of another.

• A relationship where both organisms are harmed.

• A relationship where organisms compete for the same resources.

What is commensalism?

• A relationship between two organisms in which one organism benefits and the other is unharmed.

• A relationship where both organisms benefit from each other.

• A relationship where one organism is harmed and the other is unaffected.

• A relationship where both organisms are harmed.

What happens in a predator/prey relationship?

• One organism (predator) hunts and eats another organism (prey).

• Both organisms live in harmony without affecting each other.

• The prey hunts and eats the predator.

• The predator and prey share resources equally.

What is competition in ecology?

• A relationship where both species fight for the same resources.

• A situation where species cooperate for mutual benefit.

• An interaction where one species benefits at the expense of another.

• A process where species evolve to occupy different niches.

What is the significance of symbiotic relationships?

• They illustrate the interconnectedness of species and their environments.

• They promote competition among species.

• They lead to the extinction of weaker species.

• They have no impact on the ecosystem.

How do mutualistic relationships benefit ecosystems?

• They promote biodiversity and stability by supporting various species.

• They lead to increased competition among species.

• They reduce the availability of resources for other species.

• They create a dependency that harms ecosystem resilience.

What is an example of parasitism?

• A tick feeding on a dog, benefiting while harming the dog.

• A bird building a nest in a tree without harming it.

• A bee pollinating a flower, benefiting both.

• A lion hunting a zebra for food.
