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.

What is a biotic factor?
A living factor in an ecosystem

What is an abiotic factor?
A living factor in an ecosystem

Image "B" shows more biodiversity than image "A". Why?
Because "B" shows more different species than image "A"
Because image "B" has less different species than "A"
"A" has a greater number of same species plants so this statement is wrong.
Both images show the same biodiversity
