The most notable effect of eutrophication is algal blooms. When a bloom occurs, the stream, river, lake or ocean becomes covered with algae, which is usually bright green. In addition to looking pretty ugly, it also blocks light from reaching the water. This prevents the aquatic plants from photosynthesizing, a process which provides oxygen in the water to animals that need it, like fish and crabs.]]> 2017-03-12 06:01:26 UTC https://padlet.com/tanveerfakn/sun/wish/159471521 https://padlet.com/tanveerfakn/sun/wish/159471547
1. Species diversity decreases and the dominant biota changes

2. Plant and animal biomass increase

3. Turbidity increases

4. Rate of sedimentation increases, shortening the lifespan of the lake

5. Anoxic conditions may develop

Because of the high concentration of organisms in a eutrophic system, there is often a lot of competition for resources and predator pressure. This high degree of competition and the sometimes-high chemical or physical stress make high the struggle for survival in eutrophic systems. As a result the diversity of organisms is lower in eutrophic than in oligotrophic systems.

natural run-off of nutrients from the soil and the weathering of rocks 

run-off of inorganic fertiliser (containing nitrates and phosphates) 

run-off of manure from farms (containing nitrates, phosphates and ammonia) 

run-off from erosion (following mining, construction work or poor land use) 

discharge of detergents (containing phosphates) 

discharge of partially treated or untreated sewage (containing nitrates and phosphates)

EFFECTS OF EUTROPHICATION:

• increase in plant and animal biomass 
• increase in growth of rooted plants, e.g. reeds 
• increase in turbidity (cloudiness) of water 
• increase in rate of sedimentation 
• development of anoxic conditions (low oxygen levels) 
• decrease in species diversity 
• change in dominant biota (e.g. carp replace trout and blue-green algae replace normal algae) and an 
• increase in the frequency of algal blooms.

It occurs when excessive fertilizers run  into lakes and rivers. It encourages the growth of algae.
It blocks light from reaching the water. It prevents aquatic plants photosynthesizing . So this blocks oxygen in Water to animals. ]]> 2017-03-12 06:11:31 UTC https://padlet.com/tanveerfakn/sun/wish/159471839
