Cold Desert Biome Food Web Michelle Ann Cushman BIO/101 October 20‚ 2014 Steven Peck This is a biome which is an Ocean shore environment. Animals that live here find their food in the water. Some of the Preys go on to the land to rest or reproduce‚ but food that they eat is in the water. The Artic is the area around the North Pole while the Antarctic is the area around the South Pole. Plant plankton are eaten by the Krills; the Krills are eaten by the fish‚ fish are eaten by the seals and the seals

You might have thanked the trees for giving oxygen but never phytoplankton. What can they do except try to steal the Krusty Krab formula? Well‚ what if I said that without phytoplankton‚ the entire marine ecosystem collapse‚ an increase of 1/3 accumulation of CO2‚ and oxygen drop up to 50 percent in the atmosphere‚ which will lead to human extinction. Sounds dramatic‚ but it is true. I seriously think that we need to care more about these planktons‚ since they are not unlimited in the ocean‚ and

With oceans warming up‚ toxic algae blooms are popping up all around the globe. Toxic algae blooms are very harmful and happen when phytoplankton accumulate and create toxins like domoic acid‚ which is a neurotoxin that can be deadly (Geiling). What give the phytoplankton the conditions to grow are the increasing temperatures of the oceans. Emissions are coming from places like cement production (which is a leading cause) deforestation‚ and fossil fuels like coal‚ natural gas and oil‚ which increase

labelled “osprey” PROCEDURE The pile of M&M’s represents the phytoplankton population in a lake. The printed “M” on the candy represents the amount of DDT (in ppm) the algae ingested from pesticide runoff from a nearby agricultural area. There are 100 M&M’s in the pile. Each circle below represents on phytoplankton. Mark the amount of toxin each phytoplankton has ingested. If there is a full “M” stamped on the candy then that phytoplankton has ingested 1 ppm of DDT‚ so write “1” in one of the circles

Lab Activity #3: Collection and Identification of Plankton at Lake St.George Discussion Questions 1. Phytoplankton are the organisms that were the most abundant in my sample‚ specifically from the Protista kingdom 2. I think that phytoplankton are more indicative of oligotrophic lakes‚ where-as zooplankton are more indicative of eutrophic lakes. I think this because‚ since phytoplankton are capable of producing their own energy‚ they don’t need the nutrients that eutrophic lakes offer‚ and they would
