Please see the following original paragraph, and then a paragraph based on the original sentence. Is the second paragraph plagiarized or paraphrased?
Killer Whales are well-known as predators of other marine mammals, including the large Sperm and baleen whales. Members of all marine mammal families, except the river dolphins and manatees, have been recorded as prey of Killer Whales; attacks have been observed on 20 species of cetaceans, 14 species of pinnipeds, the Sea Otter, and the Dugong. Ecological interactions have not been systematically studied and further work may indicate that the Killer Whale is a more important predator for some populations than previously believed. Not all behavioural interactions between Killer Whales and other marine mammal species result in predation, however. Some involve 'harassment' by the Killer Whales, feeding by both species in the same area, por-poises playing around Killer Whales, both species apparently 'ignoring' each other, and even apparently unprovoked attacks on Killer Whales by sea lions. These non-predatory interactions are relatively common. We conclude that interactions between Killer Whales and marine mammals are complex, involving many different factors that we are just beginning to understand.

Killer Whales prey on other marine mammals such as the large Sperm and baleen whales, and on members of all marine mammal families, except the river dolphins and manatees. Killer Whales have also attacked cetaceans, pinnipeds, the Sea Otter, and the Dugong. Some interactions be-tween Killer Whales and other marine mammal species do not result in predation, for example, "harassment" by the Killer Whales, feeding by both species in the same area, porpoises playing around Killer Whales, and even attacks on Killer Whales by sea lions. These non-predatory interactions are relatively common. Thus, interactions between Killer Whales and marine mammals are complex, and involve many different factors that we are just beginning to understand, [and] further work is necessary to understand the ecological interactions of Killer Whales.
