It depends. if the killer whale is strong enough,hungry, and maby even thretaned it can kill people. there is some cases where the person surives.
no food
1,000,000,000.
It's a matter of natural selection. If the seals weren't eaten, the the killer whales would die, causing a chain of death.
In the deep end.....
Fisherman hunt them,so they are told to attack other dolphins, but not hurt the killer whale/Orca.They die easily because the prey hunted not protected.
Because people hunt them and kill them so they die off
If they slept at all they would die
Most whales will not eat manatees, but the killer whale is an exception. Killer whales will eat manatees, dolphins, turtles, squid, and other aquatic animals.
Killer Whales have no ocean enemies except for mankind mistakes that cause species of any creature to get sick and/or die.
well for the most part, recycle. almost all of our trash that we dont recycle ends up in our oceans, the killer whale's main food source,seals, eat fish. so colored trash can look like fish, and the seals eat it. and if too many seals eat the trash, they die off, so the killer whales have nothing to eat.
no
about almost all of them but maybe 1 or 2 could die but that is it
