Biomes
Large group of ecosystems that share the same type of climax community

2. Aquatic Biomes
Marine Biomes
Freshwater Biomes
Estuaries

3. Marine Biomes Photic Zones Aphotic zone
Shallow enough for sunlight to penetrate
Bays, rocky shores, sandy beaches, and mudflats
Aphotic zone
Never receives sunlight
Least explored

4. Estuaries Partially surrounded by land Freshwater and salt water mix
Amount of Salt (salinity) depends on tide
Amount of freshwater depends on river
Grasses can grow thick forming a tangled mad that traps food material and provides habitat for developing animals

5. Freshwater Biomes Lakes Ponds Streams Rivers
Different areas in the lake provided different habitats depending on sun exposure
Ponds
Streams
Rivers

6. Aquatic Biomes Marine Estuaries Freshwater Photic zone, intertidal
Aphotic Zone

Lakes, ponds
Rivers, streams

Primary and Secondary Succession

22. Succession
The gradual supplanting of one community of plants/animals by another.

23. Primary Succession
Takes place on land where there are no living organisms.
Examples: lava flowing from a volcano, a tsunami, glaciers

24. Example of Primary and Secondary

26. Primary Succession In Action

27. Ecological Succession at Glacier Bay

28. Secondary Succession
Sequence of changes that take place after an existing community is severely disrupted in some way.
Occurs in areas that already contain life and on land that contains soil. Ex. Fire
Fire
Several years after fire

30. Secondary Succession In Action

31. Lake Succession

32. Climax Community
Stable, mature community that has little or no change.

33. Climax forest begins with a disturbance such as a fire…
