1. The energy flow to the blue whale would be from the algae and the krill
2. If the killer whale where to be removed from the ecosystem the rest of the ecosystem would increase and wouldn't have a predator to dial down the populations so it would spiral out of control
3. if the algae population increased then the the rest of the ecosystem would increase
4. the fish population would grow and the organisms that the fish feed off of would decrease leaving the rest of the ecosystem to decrease because they would need the krill and algae
