Aphids eat plant sap, and they excrete honeydew that ants can use as one source

Question

Aphids eat plant sap, and they excrete honeydew that ants can use as one source of food. Ants have been observed protecting aphids from predation by ladybugs. This is most likely an example of: a) Facultative mutualism b) Obligate mutualism c) Ectoparasitism d) Endoparasitism e) Commensalism Aphids eat plant sap, and they excrete honeydew that ants can use as one source of food. A recent study has found evidence that ants will also eat the wings off aphids and drug aphids to keep them from moving too far. This is most likely an example of: a) Facultative mutualism b) Obligate mutualism c) Ectoparasitism d) Endoparasitism e) Commensalism When the trunk or limb of a tree provides the substrate on which an epiphytic orchid grows, the arrangement benefits the orchid, which gets nutrients from the air and moisture from aerial roots while the tree is unaffected. The relationship is referred to as A) amensalism B) parasitoidism C) comensalism D) competition. When the relationship between two interacting species is detrimental to the populations of both species, the interaction is referred to as A) amensalism B) competition C) parasitism D) mutualism

Explanation / Answer

1)A)Facultative mutualism

Facultative mutualism:Each species gain benefit in the presence of the other but each can still survive without the other.

2)C)Ectoparasitism

A parasite that lives in skin on or not with in the body.

3)C)Commensalism

Commensalism : It is a type of association in this one individual get benefited the other is neither helped or harmed.

4)A)Amensalism

Ammenalism: In this one orgaism is destroyed and the other organism is unaffected.
