Fresh water ecosystems

Fresh water ecosystems

Key Vocabulary: ecosystems,

eutrophication, hypoxia, bioindicators, point source pollution, non-point source pollution, biotic, abiotic

Fresh water ecosystems

a biological (Biotic=living) community of interacting organisms and their physical environment (abiotic=non living).

**take note of the abiotic factors we have been talking about recently

Ecosistemas de agua dulce

una comunidad biológica (biótica = viva) de organismos que interactúan y su entorno físico (abiótico = no vivo).

What abiotic factors did you notice from the video that we have learned about recently

Lets tie it all together

• freshwater scarcity

• Catawba River Basin- Fresh water ecosystems

• Nutrient pollution- Eutrophication & Hypoxia (NO OXYGEN)

• Human impact and what we can do

Freshwater in the Catawba river basin

• streams

• rivers

• ponds

• lakes

• swamps

Scarcity

We know that in some areas we use water faster than it can be replenished. We also know that some of the scarcity is due to the condition of the water

Nutrient pollution

• excess nutrients get into the water

• traceable pollution is known as point source pollution

• untraceable pollution is called nonpoint source pollution

contaminación de nutrientes

• el exceso de nutrientes entra en el agua

• La contaminación rastreable se conoce como contaminación de fuente puntual.

• La contaminación imposible de rastrear se llama contaminación de fuente difusa.

Bio indicators

If a body of water is hypoxic (low or no oxygen) what do you think will happen to the bio indicators in that body of water?
