Ecological Succssion

The process of one ecological community changing into another one.

Role: for an ecosystem to reach a state of balance or rest after it has been formed or disturbed

Primary Succession

  • Lichens and moss (pioneer species) appear

  • Breaks down rock to create soil

  • Grass and weeds

  • Small trees

  • Large trees

  • Climax Community

6

Multiple Choice

Secondary Succsion

  • Forest

  • Disturbance occurs (Catastrophic event)

  • Everything is dead

  • Soil is still present

  • Pioneer Species: Grass and weeds

  • Small animals and plants, Small trees....Tall trees

  • Climax Community

Human Impact on Ground & Surface Water

22

Vocabulary

  • Surface Water = pond, lake, stream, ocean

  • Watershed = streams, rivers that all drain into a larger body of water such as a larger river, or an ocean.

  • Water table = line that separates saturated & unsaturated

  • Aquifer = full body of groundwater (contains it)


media

23

Pollutants

  • Oil Spills

  • Factories

  • Algae

  • Gas Station -- Oil

  • Landfills - waste

  • Farm -- Pesticides, Fertilizer

  • Livestock - waste

24

Multiple Select

Which factors are apart of agricultural pollution?

1

Bacon

2

Pesticides

3

Manure

4

Fertilizer

25

Multiple Choice

When fertilizers enter surface water, they cause problems in

the watershed by -

1

increasing the amount of nutrients available to fish in lakes and streams.

2

clogging narrow streams and preventing water from flowing properly.

3

raising the water level in nearby rivers to levels leading to flooding.

4

causing rapid algae growth that decrease oxygen levels and choke aquatic life.

26

Multiple Choice

Where is groundwater found?

1

Cracks of rocks under the earth’s surface and soil pores

2

In caves, streams, rivers, and oceans

3

Falling rain water

4

None of the above

27

Is this groundwater or surface water?
