The symbiotic relationships are classified as parasitism (one organism benefits while the other is harmed), mutualism (both organisms benefit), and commensalism (one organism benefits while the other is neither helped nor harmed). The examples given illustrate these types of symbiotic relationships in various life forms.
Answer for questions 1-3: The type of symbiosis where one organism is helped while the other is harmed is parasitism. When both organisms benefit it is termed mutualism. When one organism benefits and the other is neither helped nor harmed it is commensalism.
Answer for question 4: Fleas and ticks sucking blood and potentially harming dogs or cats is an example of parasitism.
Answer for question 5: The yucca moth and yucca plant relationship exemplifies mutualism, as the larvae get food and the yucca plant gets pollinated.
Answer for question 6: Athlete's foot fungus thriving on a human causes harm to the host and signifies parasitism.
Answer for question 7: Barnacles living on whales without causing them harm is a case of commensalism.
Answer for question 8: Mosquitoes feeding off humans by biting is another example of parasitism.
Answer for question 9: Birds cleaning alligators' teeth without harm and gaining food is a type of mutualism.
Answer for question 10: When one organism benefits at the expense of another, as in 'Good for you, bad for me,' it reflects parasitism. 'Good for me, doesn't bother you,' aligns with commensalism since one species benefits and the other remains unaffected. 'Good for me, good for you,' typifies mutualism, where both species benefit.
