Question

Which of the following are symbiotic relationships? Select all that apply.

An organism of one species benefits and an organism of a different species
also benefits.
An organism of one species benefits and an organism of a different species
is harmed.
An organism of one species benefits and an organism of a different species
is not significantly affected.

Answer 1

Symbiotic relationships are interactions between organisms of different species, and there are three types: mutualism, parasitism, and commensalism. In mutualism, both organisms benefit; in parasitism, one organism benefits while the other is harmed; in commensalism, one organism benefits while the other is not significantly affected.

Step-by-step explanation:

Symbiotic relationships are interactions between organisms of different species that involve a close and long-term association. There are three types of symbiotic relationships:

1. Mutualism: Both organisms benefit from the relationship. For example, the relationship between bees and flowers, where bees benefit from nectar while flowers benefit from pollination.
2. Parasitism: One organism benefits while the other is harmed. A common example is ticks feeding on the blood of animals.
3. Commensalism: One organism benefits while the other is not significantly affected. An example is remora fish attaching themselves to sharks to feed on scraps.

So, the correct options from the given choices are:

• An organism of one species benefits and an organism of a different species also benefits.
• An organism of one species benefits and an organism of a different species is harmed.
• An organism of one species benefits and an organism of a different species is not significantly affected.

Answer 2

Symbiotic relationships include mutualism where both species benefit, commensalism where one benefits and the other is unaffected, and parasitism where one benefits and the other is harmed.

Step-by-step explanation:

The symbiotic relationships where different species interact with each other include mutualism, commensalism, and parasitism. In a mutualistic relationship, both species benefit. An example of this would be bees pollinating flowers; the bees get nectar for food, and the flowers are pollinated. In a commensal relationship, one species benefits while the other is not significantly affected, such as a barnacle attaching itself to a whale's skin.

The barnacle gets a place to live and catch food particles without harming the whale. Lastly, in a parasitic relationship, one species benefits at the expense of the other, such as a tick feeding on a dog's blood. The tick gets nourishment while the dog may be harmed through blood loss and potential diseases.
