Module 8: Marine Ecology

This Thursday is our last class before Christmas break. Those students who have not given me your test scores, please do so in class.  The first period class decided to draw names for a gift exchange.  The second period class decided to have a secret Santa gift exchange. There is a $5.00 limit.

Food Webs of the Ocean

Feeding relationships are often shown as simple food chains – in reality, these relationships are much more complex, and the term ‘food web’ more accurately shows the links between producers, consumers and decomposers.  A food web diagram illustrates ‘what eats what’ in a particular habitat. Pictures represent the organisms that make up the food web, and their feeding relationships are typically shown with arrows. The arrows represent the transfer of energy and always point from the organism being eaten to the one that is doing the eating. Organisms in food webs are commonly divided into trophic levels. These levels can be illustrated in a trophic pyramid where organisms are grouped by the role they play in the food web.

Observe carefully below as students demonstrated what a food web really looks like.

Man’s activities and natural disasters have led to a reductions in our natural reef systems. Recreationally, growth in sports fishing, scuba diving, and boating has increased the pressures on these systems. Commercially, our seafood industry is dependent on developing the ocean to enable ever larger, yet sustainable, harvests. The loss of our natural systems, coupled with increased use, compels us to do everything we can to save natural reefs. Even so, the natural reefs cannot rebuild themselves fast enough to meet human demands. Long lasting artificial reefs are useful tools for restoring our reef systems to a natural and productive balance. In class we watched NetFlex Season 3 Episode 12 Dirty Jobs with Mike Rowe as he was in Sarasota at Reef Innovations learning to build reef balls.

    It sounds like your class is having quite a bit of fun 😉
    As a former student… I know the class can be difficult at times, but hang in there and don’t lose steam! You will be happy later on knowing that you completed something worth while.
    TIP: here is a little secret… Mrs. Smith loves it when you do a little extra credit and put your mind into your work. Trust me… you want to be on her good side 😉
