select the text from the paragraph that best helps you understand that host means an organism that another organism lives on. there may be more than one correct choice. parasitic relationships are often the most familiar types of symbiotic relationships. a common example is a flea living on a dog. in cases like these, the parasite gains a viable habitat to support its life cycle, while the host is harmed.
Answer
Brief Explanations:
The example of a flea living on a dog shows one organism (flea) living on another (dog), which helps define the host - the dog in this case. The statement about the parasite gaining a habitat while the host is harmed also implies the nature of the host as the organism being lived on.
Answer:
"A common example is a flea living on a dog." and "the parasite gains a viable habitat to support its life cycle, while the host is harmed."
