Symbiotic Relationships

What is mutualism?

• Mutualism is a type of competition where two species fight for resources.

• Mutualism is a type of symbiotic relationship where both species involved benefit from the interaction.

• Mutualism is a type of parasitic relationship where one species benefits at the expense of the other.

• Mutualism is a type of commensalism where one species benefits and the other is unaffected.

Give an example of mutualism in nature.

• Bees and flowers

• Sharks and fish

• Lions and zebras

• Cats and mice

Explain commensalism.

• Commensalism is a type of relationship where both species benefit equally.

• Commensalism is a type of relationship between two species in which one species benefits while the other is neither helped nor harmed.

• Commensalism is a type of relationship where one species always harms the other.

• Commensalism is a type of relationship where one species benefits at the expense of the other.

Provide an example of commensalism.

• The relationship between sharks and remora fish.

• The relationship between barnacles and whales.

• The relationship between bees and flowers.

• The relationship between lions and zebras.

Define parasitism.

• Parasitism is a type of symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host). The parasite derives nutrients or other benefits from the host, often causing harm to the host in the process.

• Parasitism is a type of mutualistic relationship where both organisms benefit from each other

• Parasitism is a type of competition where two organisms fight for the same resources

• Parasitism is a type of commensalism where one organism benefits and the other is unaffected

Name a common parasite and its host.

• Fleas in the hair of its host, such as dogs or cats

• Mites in the skin of its host, such as humans or animals

• Ticks in the blood of its host, such as humans or animals

• A common parasite is the tapeworm, which can be found in the intestines of its host, such as humans or animals.

How do organisms benefit from mutualism?

• By receiving resources or services from their mutualistic partner, such as food, protection, or pollination.

• By being isolated from other organisms

• By receiving harmful substances from their mutualistic partner

• By competing for resources with their mutualistic partner

In commensalism, how does one organism benefit while the other is unaffected?

• One organism benefits while the other is unaffected because the benefiting organism gains resources or shelter without affecting the other organism.

• One organism benefits while the other is unaffected because they both have a negative impact on each other.

• One organism benefits while the other is unaffected because they compete for resources but do not harm each other.

• One organism benefits while the other is unaffected because they both rely on each other for survival.

What is the difference between parasitism and mutualism?

• In parasitism, one organism benefits at the expense of the other, while in mutualism, both organisms benefit from each other.

• Parasitism and mutualism are the same thing.

• In parasitism, both organisms benefit from each other, while in mutualism, one organism benefits at the expense of the other.

• In mutualism, one organism benefits at the expense of the other, while in parasitism, both organisms benefit from each other.

Explain how parasitism can be harmful to the host organism.

• Parasitism can be harmful to the host organism due to the parasite feeding on the host's resources, weakening the host's immune system, and causing damage to the host's tissues and organs.

• Parasitism can be harmful to the host organism by promoting the host's overall health and well-being

• Parasitism can be harmful to the host organism by increasing the host's reproductive success and survival rate

• Parasitism can be harmful to the host organism by providing beneficial nutrients and support to the host's immune system
