Ecological Relationships and Interactions

This video explores ecological relationships, dividing them into intraspecific and interspecific categories. Intraspecific relationships occur within the same species, while interspecific relationships occur between different species. Both types can be harmonic (beneficial) or disharmonic (harmful). Examples include mutualism, protocooperation, and predation. The video emphasizes the importance of these relationships in maintaining ecological balance.

What are the two main types of ecological relationships?

• Mutualism and Parasitism

• Predation and Competition

• Intraespecific and Interspecific

• Harmonic and Disharmonic

Which of the following is an example of an intraespecific harmonic relationship?

• Parasitism

• Mutualism

• Colonies

• Predation

In which type of relationship do individuals of the same species compete for resources?

• Mutualism

• Commensalism

• Competition

• Inquilinism

What is mutualism?

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

• A relationship where both species benefit

• A relationship where one species lives on or in another species

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

Which of the following is an example of protocooperation?

• A tick feeding on a dog

• A lion hunting a zebra

• A fungus releasing antibiotics

• A bird eating parasites off a larger animal

In which relationship does one species benefit from the food scraps of another without harming it?

• Mutualism

• Commensalism

• Parasitism

• Predation

What is the primary characteristic of a disharmonic relationship?

• Both species are harmed

• Neither species is affected

• One species is harmed

• Both species benefit

Which of the following is an example of parasitism?

• A bird eating parasites off a larger animal

• A tick feeding on a dog

• A lion hunting a zebra

• A fungus releasing antibiotics

What is amensalism?

• A relationship where one species lives on or in another species

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

• A relationship where both species benefit

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

Why are ecological relationships important?

• They prevent any species from being harmed

• They determine how species interact with their environment and each other

• They help species to avoid competition

• They ensure that all species benefit equally
