Which of the following is not an example of commensalism-a)Egret bird ...
Explanation:
Commensalism is a type of symbiotic relationship between two organisms in which one organism benefits while the other organism is neither harmed nor helped. Therefore, the correct option is:
D) Plover bird and crocodile - This is not an example of commensalism as the plover bird benefits by feeding on the food particles present in the teeth of the crocodile, while the crocodile is not benefited nor harmed by the presence of the plover bird. This is an example of mutualism as the plover bird benefits while helping the crocodile by cleaning its teeth.
Other examples of commensalism are:
A) Egret bird and cattle - The egret bird benefits by feeding on the insects present on the cattle, while the cattle is not benefited nor harmed by the presence of the egret bird.
B) Sea anemone and clown fish - The clown fish benefits by living among the stinging tentacles of the sea anemone which protects it from predators, while the sea anemone is not benefited nor harmed by the presence of the clown fish.
C) Pilot fish and shark - The pilot fish benefits by feeding on the scraps of food left by the shark, while the shark is not benefited nor harmed by the presence of the pilot fish.
Which of the following is not an example of commensalism-a)Egret bird ...
Explanation:
Commensalism is a relationship between two organisms in which one benefits and the other is neither helped nor harmed. In this type of interaction, one species benefits while the other is not affected.
a) Egret bird and cattle: Egret bird feeds on the insects that are found on the cattle. The cattle are not affected by the bird's presence, while the bird is benefiting from the insects it eats. This is an example of commensalism.
b) Sea anemone and clown fish: Clown fish live among the tentacles of sea anemones. The fish are protected from predators by the anemone's stinging tentacles, and in turn, the anemone is not affected by the presence of the fish. This is an example of commensalism.
c) Pilot fish and shark: Pilot fish swim alongside sharks, feeding on scraps of food left behind by the shark. The shark is not affected by the presence of the fish, while the fish is benefiting from the food it eats. This is an example of commensalism.
d) Plover bird and crocodile: The plover bird feeds on the food that is found in the crocodile's teeth. The crocodile is not affected by the presence of the bird, while the bird is benefiting from the food it eats. However, this is not an example of commensalism as the plover bird is actually helping the crocodile by cleaning its teeth, thus it is a mutualistic relationship.
Therefore, option D is not an example of commensalism.
