If the penguins from Ecosystem B were all to die from disease, what would happen to the other organisms?
If the penguins were to die, the whales would lose their major food source. Although they can still eat krill, penguin were their favorite, so the ecosystem would collapse.
If the penguins were to die, the squid would lose their major food source. This would not make the ecosystem collapse, since the squid can still hunt the seagulls and seals.
If the penguins were to die, the plankton would lose their major food source. This would make the ecosystem collapse since the plankton are this food web's foundation.
If the penguins were to die, the seals would lose their major food source. This would allow more squid and plankton to be available to other organisms. Since the seal has other food sources (squid), the ecosystem should not completely collapse.
