ECOSYSTEM ECOLOGY Flashcards
is a large area characterized by its vegetation, soil, climate, and wildlife.
biome
five major types of biomes
aquatic, grassland, forest, desert, and tundra.
are bodies of water surrounded by
land—such as ponds, rivers, and lakes—that have a salt
content of less than one percent.
Freshwater biomes
the study of inland waters
Limnology
inland waters
⦁ lakes (both freshwater and saline)
⦁ reservoirs
⦁ streams
⦁ wetlands
⦁ groundwater
The limnological discipline integrates the _________, _____, ____, and _____ with ___ and describes and evaluates how ___, ___, and ________________.
functional relationships of growth, adaptation, nutrient cycles, and biological productivity with species composition,
how physical, chemical, and biological environments regulate these relationships.
The word limnology is derived from the Greek word _____ and _______.
limne (marsh, pond)
limnaea (a thing pertaining to a marsh).
the study of the structure, function, and change of organisms in freshwaters as affected by their dynamic physical, chemical, and biotic environments.
a subset to Earth’s aquatic ecosystems
Freshwater Ecology
freshwater includes
⦁ lakes and ponds
⦁ rivers
⦁ streams
⦁ springs
⦁ bogs
⦁ wetlands
Freshwater habitats can by classified by different factors:
⦁ temperature
⦁ light penetration
⦁ nutrients
⦁ vegetation
Freshwater ecosystems can be divided into:
⦁ Lentic Ecosystems (still water)
⦁ Lotic Ecosystems (flowing water)
Importance of Freshwater Ecosystem
⦁ flood control
⦁ water purification
⦁ shoreline stabilization
⦁ sequestration of carbon dioxide
Freshwater Ecosystems (vegetated wetlands) play an important role in _______.
mitigation against climate variability
Freshwater Ecosystem Examples
⦁ Streams
⦁ Rivers
⦁ Lakes
⦁ Marsh
largest lake in the PH
Laguna Lake
second largest lake in the PH
Lake Lanao
deepest lake in the PH
Lake Mainit
example of marsh in PH
Agusan Marsh
supplies many kinds of habitats that support marine life
marine environment
supplies many kinds of habitats that support marine life
marine environment
Marine biomes include:
the ocean
coral reefs
estuaries
are habitats that support marine life
Marine habitats
Marine life depends in some way on the ____ that is in the sea.
saltwater
the term marine comes from the Latin word
mare (sea or ocean)
Marine habitats can be divided into
Coastal Habitats,
Open Ocean Habitats
⦁ found in the area that extends from as far as the tide comes in on the shoreline out to the edge of the continental shelf.
⦁ most marine life is found in _____, even though the shelf area occupies only seven percent of the total ocean area.
Coastal Habitats
found in the deep ocean beyond the edge of the continental shelf.
Open Ocean Habitats
the lowest ecological zone in a water body, and usually involves the sediments at the seafloor.
benthic zone
Mangrove Ecosystem Services (the benefits people derive from mangroves)
- Wood
- Livelihoods
- Climate Regulation
- Fisheries
- Tourism
- Water Filtration
- Coastal Protection
a transitional area of vegetation between two different plant communities
