The rise of toxic Microcystis algae blooms in Lake Eerie A combination of climate change and agricultural practices have led to an excess run off of phosphorus in Lake Erie‚ resulting in excess algae blooms spread across the surface of the water. Phosphorus is the key nutrient that dictates algae growth and abundance. Microcystis‚ a species of cyanobacteria characterized by its blue colour continually contaminates the waters‚ and damages marine ecosystems‚ due to its toxicity. Being the smallest

1.2 How have environmental cycles changed? The capacity of ecosystems to provide benefits to humans‚ that is to provide ecosystem services‚ derives from environmental cycles of water‚ nitrogen‚ carbon‚ and phosphorus. These processes have in some cases been significantly modified by human activity. Changes have been more rapid in the second half of the 20th century than at any other time in recorded human history. Water cycle: Water withdrawals from rivers and lakes for irrigation‚ urban uses‚

Unit 3. Assignment 1: Bacterial Growth Rates 1. Mediums that could be used to determine shigellosis include Btilliant Green Agar‚ and Triple Sugar-Iron Agar. Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with

Name: Donnavon Williams Date: 8-4-13 Student Exploration: Water Pollution Vocabulary: Bacterial pollution- Bacteria play a vital role in processes such as decomposition and digestion. Nutrient pollution- Fuels the growth of algae blooms that block sunlight from reaching bay grasses and rob the water of oxygen. Sediment pollution- Sediment is soil particle that have entered creeks‚ rivers and lakes. Toxic pollution- In our environment threaten our rivers and lakes‚ our air‚ land‚ and

In 2010‚ the Gulf of Mexico was the largest ever recorded dead zone of 7‚700 square miles. Seven years later‚ the zone is still growing; the Gulf’s dead zone is now up to 8‚776 square miles‚ larger than the size of New Jersey. The dead zone is caused by excess nutrients entering the water. Iowa’s waters are polluted by different causes affecting humans‚ and the growth of organisms. Agriculture and nutrient runoff can cause algae to overpopulate an area‚ using up more oxygen‚ leading to not enough

Carbon‚ Phosphorus‚ and Nitrogen Cycles By: Amy Gentry There are three importation cycles that the environment. The three cycles are carbon‚ phosphorus and nitrogen cycles. These cycles are part of photosynthesis. These are a chain that keeps everything going in the word. These cycles keep animal alive and plants and people breathing. Carbon cycle is an Importation one of the cycle on earth. You get carbon atoms from co2 then become carbon atoms of the organic molecules are making up the plant

Water Quality and Contamination Melody McBride SCI-207 Dependence of man on the environment Robin Glenn September 28‚ 2014 Abstract The lab was conducted at the McBride residence. For this experiment vegetable oil‚ vinegar and liquid detergent was use to contaminate the water. Testing of how ground water is affected by different contaminants was the bases of the experiment. The results were interesting in that when vinegar is filtered through dirt it came out fairly clean‚ it also

BIOLOGY PRACTICAL ASSIGNMENT NAME OF INVESTIGATION: Effect of Eutrophication on Plant Growth RESEARCH QUESTION: How does the process of Eutrophication affect the growth of Duckweed? HYPOTHESIS: In this experiment‚ we are basically testing the use of different fertilizers on the growth of Duckweeds. Plants need fertilizers for their growth and to increase the yield of crops. But‚ at the same time‚ it depends on which Fertilizer being used and in how much proportion. Does it have sufficient nutrients
