Plankton... November 25, 2013

Plankton is important to the marine food web because is it a major food source for all organisms. The two main types of phytoplankton are diatoms and dinoflagellates. The two main types of zooplankton are holoplankton and meroplankton. Plankton is beneficial because phytoplankton can produce it's own food, both are a major food source for marine life, and they are a large portion of the food web. This effects daily life because we eat the animals that eat plankton.

Plankton... November 17, 2013

Plankton are important to the food web because phytoplankton can produce it's own food and many organisms fee off of them. Some of their adaptions include spikes and projections, the release of oil, and air-filled floats. An example of phytoplankton is a protist and an example of zooplankton is picoplankton. Phytoplankton can photosynthesize and zooplankton have flagella that move them around like animals.

Anchor November17, 2013

Anchors are used by all boaters and any oceanographers who need to use boats to collect data. Anchors are dropped from boats and stuck in the ground under the water. With the anchor in the ground, the boat stays in place above the surface and allows divers to go under water to collect the required data without worrying about their boat moving above them.
