The lionfish is a venomous fish found primarily in the Red Sea and the Indian Ocean. In the 1990s, lionfish were accidentally released into the Atlantic Ocean, where they found abundant resources and favorable environmental conditions. Which of the following scenarios is most likely to result in the lionfish having a major impact on the communities into which they were introduced?
With no natural predators, the lionfish population will become very large.
Some native species of invertebrates will develop a resistance to lionfish venom.
Random mating will allow the lionfish population to reach Hardy-Weinberg equilibrium.
A virus that specifically infects lionfish will become more prevalent.
There is strong evidence that two species of
cliff-dwelling birds have nested in the same
environment and fed in the same water for
thousands of years, with each having stable
population sizes. Based on this information,
which of the following statements is the best
conclusion?
The two birds compete for food.
One species will displace the other.
The two birds have different ecological niches that allow coexistence.
One species eats a more diverse diet than the other does.
Which would result in primary succession?
volcano destroying habitat leaving only soil and ash
Tornado destroying a crop leaving very little soil
Glacier retreating exposing bare rock
limiting factors
