Ecological Relationships

What defines a predatory ecological relationship?

• Both organisms benefit from the interaction.

• One organism benefits, and the other is harmed.

• One organism hunts and kills another for food.

• Organisms compete for the same limited resources.

Which statement about roles in food chains is supported by the video?

• An organism can only be a predator and never be prey

• Once an organism is a prey, it cannot be a predator

• An organism can be both predator and prey depending on context

• Predators never face threats from other species

Which of the following is an example of competition for an abiotic factor?

• Antlions and jumping spiders both hunting ants.

• Two antlions fighting over a single ant.

• Fleas feeding on a dog's blood.

• Two plants growing close together and vying for sunlight.

In a parasitic relationship, how do the organisms involved typically interact?

• Both organisms benefit from the interaction.

• One organism benefits, and the other is harmed.

• One organism benefits, and the other is unaffected.

• Both organisms are harmed due to limited resources.

The acacia tree and acacia ants example is used to illustrate which type of symbiotic relationship?

• Competition

• Mutualism

• Commensalism

• Parasitism

What is the primary difference between mutualism and commensalism?

• Mutualism involves one organism benefiting and the other being harmed, while commensalism benefits both.

• Mutualism benefits both organisms, while commensalism benefits one and the other is unaffected.

• Mutualism involves competition for resources, while commensalism involves a predator-prey relationship.

• Mutualism is a short-term interaction, while commensalism is a long-term interaction.

The barnacle–whale relationship in the video is presented as an example of:

• Mutualism

• Commensalism

• Parasitism

• Predation
