Achemical spill has just killed off all the algae in a part of the open ocean. how will this affect the food webs in that part?

Most affected will be the creatures that eat algae (like whales, flamingo etc.) 
next the creature that eat them and that they also eat 
then gradually the web spreads affecting both prey and predator of the animals 

When the ball is rising up, it gains kinetic energy. when the ball reaches the very top, it will have all potential energy, until it falls back down and gains it kinetic energy. finally when you catch the ball or it falls back down, it would have gained its potential energy back.

Iwould say silver and gold
