Final answer:
In symbiotic relationships, organisms are not always harmed. Different types of symbiotic relationships exist, including mutualism, commensalism, and parasitism, which have varying effects on organisms involved.
Step-by-step explanation:
In symbiotic relationships, the effect on organisms can vary, and they are not always harmed. Symbiotic relationships can be classified into three main types: mutualism, commensalism, and parasitism.
In mutualism, both organisms involved benefit from the relationship. For example, the relationship between bees and flowers is mutualistic, as bees get food (nectar) from the flowers while pollinating them.
In commensalism, one organism benefits while the other is neither harmed nor helped. An example is the relationship between a remora fish and a shark, where the remora fish gets protection by attaching itself to the shark's body without harming it.
In parasitism, one organism benefits (parasite) while the other is harmed (host). For instance, ticks and fleas are parasites that feed on the blood of their hosts, causing harm and discomfort.
