Eutrophication

Is the process through which a body of water becomes enriched with nutrients, often leading to excessive plant growth and decay resulting in oxygen depletion.

Which of the ecosystems would plants be attached to rocks or logs or water

river

UAHS

raingardens near tennis courts with native plants tend to soack up water to prevent floods and obsorb extra nutrients

2- tree canopy cover reduces temp helps air pollution.

Which ecosystem is sued for breeding?

wetlands 

Where do we get water?

Groundwater

Desalination saltwater

Surface water

Storm water management

Rain or snow that flows over surfaces like streets and parking lots instead of soaking in the ground. Sediments and toxins are swept up into local waterways. 

vegetated buffer zones

surrounds agricultural fields, also controls stabilization and provides good erosion, and adsorb nutrients. 

Tree canopy cover 

Canopy trees have layers of leaf branches, stems of trees that cover the ground and reduces heat temp. 

Sponge cities 

in urban areas that reduce flooding 

Impervious surfaces

Things that prevent water from slipping off the ground for example rooftops or chairs like outdoor benches.

Biological oxygen demand

amount of oxygen needed

channelization

modifying the path of water

Rain gardens 

native shrubs in a small dep
