Part A Assess whether the current dramatic decline in sharks is more likely the effect of background extinction or a mass extinction. (Some shark populations have dropped to just 5 percent of their former abundance over the past few decades due to overfishing.) O Overfishing is more similar to a mass extinction event than to background extinction, because sharks are harvested no matter how well adapted they are to their environment. O Overfishing is more similar to a background extinction than to a mass extinction because the decline in shark populations is happening slowly. O Overfishing is more similar to a background extinction than to a mass extinction because fishing is like a predator/prey interaction. O Overfishing is more similar to a mass extinction event than to background extinction because sharks are not well adapted to their environment. Submit Request Answer
