G4 3Q SCI Symbiosis

What are the three main types of symbiosis?

• mutualism, commensalism, and parasitism

• mutualism, predation, competition

• parasitism, predation, cooperation

• predation, cooperation, competition

Define mutualism and provide an example of a mutualistic relationship.

• Mutualism is a type of parasitic relationship where one species benefits at the expense of the other. An example is the relationship between ticks and dogs, where ticks feed on the blood of dogs.

• Mutualism is a type of competition where two species fight for the same resources. An example is the relationship between lions and hyenas, where both compete for the same prey.

• Mutualism is a type of commensalism where one species benefits and the other is unaffected. An example is the relationship between barnacles and whales, where barnacles attach to the whale's skin and benefit from the transportation and food availability, while the whale is not affected.

• Mutualism is a type of symbiotic relationship where both species benefit from the interaction. An example of mutualism is the relationship between bees and flowers, where bees pollinate the flowers and in return, the flowers provide nectar for the bees.

Explain commensalism and give an example of a commensal relationship.

• The relationship between bees and flowers, where bees benefit from collecting nectar and pollen, while flowers are negatively affected by the loss of their resources

• The relationship between lions and zebras, where lions benefit from hunting and eating zebras, while zebras are negatively affected by the loss of their population

• An example of a commensal relationship is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit from the transportation and food particles stirred up by the whale's movement, while the whale is not affected by the presence of the barnacles.

• The relationship between sharks and remoras, where sharks benefit from the remoras cleaning their skin, while remoras are negatively affected by the risk of being eaten by the shark

Describe parasitism and provide an example of a parasitic relationship.

• The relationship between a tick and a dog, where the tick feeds on the dog's blood, is an example of parasitism.

• The relationship between a human and a pet, where the human takes care of the pet, is an example of parasitism.

• The relationship between a bee and a flower, where the bee helps in pollination, is an example of parasitism.

• The relationship between a lion and a zebra, where the lion hunts and kills the zebra for food, is an example of parasitism.

How do mutualistic relationships benefit both organisms involved?

• By providing resources, protection, or other advantages that help each organism survive and thrive.

• By competing for resources and causing stress to both organisms

• By creating imbalance in the ecosystem and leading to the extinction of one organism

• By causing harm and reducing the population of one organism

Give an example of a mutualistic relationship between a flower and a bee.

• Cats and dogs

• Bees and flowers

• Trees and rocks

• Lions and zebras

Explain how clownfish and sea anemones demonstrate a symbiotic relationship.

• They demonstrate a mutualistic relationship where the clownfish is protected by the sea anemone's stinging tentacles, and in return, the clownfish helps to attract prey and removes parasites from the sea anemone.

• The clownfish feeds on the sea anemone's tentacles, weakening it and causing harm

• The sea anemone provides food for the clownfish, while the clownfish protects the sea anemone from predators

• They compete for food and territory, often resulting in the death of one of the species

Describe the relationship between oxpeckers and large mammals in the African savanna.

• Parasitic

• Mutualistic

• Predatory

• Competitive

How does symbiosis contribute to the stability of an ecosystem?

• Having no impact on the stability of the ecosystem

• Leading to the extinction of certain species

• Causing competition and conflict among different species

• Promoting balance and cooperation among different species

Provide an example of how a predator-prey relationship can be considered a form of symbiosis.

• A predator-prey relationship is when two organisms benefit from each other's presence.

• A predator-prey relationship is when two organisms have a neutral interaction with each other.

• A predator-prey relationship can be considered a form of symbiosis.

• A predator-prey relationship is when two organisms have a parasitic relationship.
