Marine food web

I was a Sperm whale in the food web activity. Sperm Whales are known to eat squid, anchovies, octopus, Cephalopods, cuddle fish and a variety of other fish. If the squids were to become extinct it would be difficult for the sperm whale to survive. It would have to rely on other species such as the octopus and other fish species.

Phytoplankton 

Phytoplankton are important because they are the beginning of the food chain for most of the planet. The smaller organisms eat the phytoplankton then larger organisms eat the smaller ones. 

Energy flow

 There are different tropic levels and as you move up the food web the animal become bigger and bigger.

Human impacts

Humans can greatly effect the marine food web. If a certain species was fished or hunted a lot they could be come endangered and other organisms who feed off of that species would suffer greatly.
