Eutrophication Essay
❖ Is the process which start with the addition of excess nutrients to water(river, lakes, ponds) and ends with the collapse of the aquatic ecosystem
❖ Sewers, abattoirs, farm animals
❖ And run-off of fertilizers from crops to rivers
❖ Resulting in addition of excess nutrients phosphate into rivers
❖ The increase OE nutrients in water
❖ Causes pants such as alga
❖ To flourish to such an extend all water becomes covered
❖ Light an no longer penetrate below water surface
❖ Which cause deeper dwelling of aquatic life to die
❖ Resulting in no release of oxygen during photosynthesis
❖ Oxygen supply for aquatic animals decline
❖ Leading to death of aquatic life
❖ Decomposition of dead plants and animals
❖ Introduces further usage of oxygen
❖ With methane being released
❖ Giving dams a strong smell of purification
❖ Resulting to unhealthy dams to ecosystem
❖ And collapse of its aquatic food webs and pyramids
Thread To Biodiversity
The greatest thread to biodiversity is the destruction of habitats.
Describe how the various human activities may lead to habitat loss.
Describe how the various human activities may lead to habitat loss.
Urbanization
❖ Land is cleared for housing, industries and roads
❖ Leading to habitat fragmentation
❖ Causing some populations to become extinct
Deformation
❖ The demands for wood products caused clearance of many plants
❖ Destroying the ecosystem of some populations
❖ Leading to extinction of some populations
Destruction of wetlands and grasslands
❖ Areas are cleared for human inhabatiions
❖ Reducing biodiversity of organisms
❖ That depend on these lands
Golf estates
❖ Requires plenty of water to vast clearance of vegetation
❖ So that only few species exist.
Mining
❖ Results in degradation of water and the PH of the environment
❖ Causes soil erosion
❖ No species can exist t mine areas
Poor farming methods
❖ Monoculture allow few of species to survive
❖ Losing large amount of plants and animals
❖ Due to non crop varying
Overgrazing
❖ Lead to loss of topsoil
❖ Decreasing soil fertility
Use of pesticides
❖ Kills secondary consumers
❖ Leading to extinction of some populations
