Chapter 20 Flashcards
All the living things in one area and the non living environment they interact with is called.
Ecosystem
Study of an ecosystem usually focuses on two thing
Energy flows
Nutrient cycle
Energy enters the livining system via
Producers
Sunlight and photosynthesis
The amount of energy captured from photosynthesis
Productivity
Is the amount of energy that makes it into tissues of photosynthesizers
Net Primary Productivity
The engergy is passed throught the food chain in different levels called
Trophic levels
Herbivores
Carnivores
Omnivores
Decomposers
Trophic level 1
Producers
Trophic level 2
Primary Consumer
Trophic level 3
Secondary Consumer
Trophic level 4
Tertiary Consumer
How much energy makes it to the next Trophic level
10-20%
Limits level of food chain
4 of the nutrients cycled through ecosystem
Water
Carbon
Nitrogen
Phosphorus
Water cycle where is the water found
Oceans 96%
Ice (ice caps and glaciers)1.5-2%
groundwater 1.5- 2%
surface freshwater 1%
Water vapor 0.001%
Ways water cycles through the ecosystem
Precipitation
Evaporation
Changing locations
(Runoff and other movement)
Respirations and Transpiration
Carbon Cycle transisitons
Photosynthesis
Respiration
Geological processes
Combustion
Carbon Pools
CO2 in air and water
Organic CO2 in living things/decomposing matter
Fossil fuels
Annual weather patterns
temperature
rainfall
Climate
Latitudes where air rises and cools
More precipitation
Latitudes where air sinks and warms
Less precipitiation
The differnet types of Ecosystems
Ocean 71%
Freshwater 2%
Terrestrial Biomes 25-30%
Three types of ocean ecosystems
Shallow water intertidal zones
Open-Sea 40% of photosynthesis
Deep-Sea waters
Types of freshwater ecosystems
River and Streams
Lakes and Ponds
Wetlands
Swamps & Marsh
Bog & fen
Difference between (Swamps & Marsh) and (Bog &Fen)
Swamps & Marsh have surface water
Bog & fen have surface vegetation
Difference between Swamp & Marsh
Swamps have trees
Marsh do not have trees
Difference between Bog & Fen
Bog saturated soil and acidic
Fen is a wetland and alkaline
Lake and pond zones
Littoral
Limnetic
Profundal
Diffeence beween Littoral, Limnetic, and Profundal
Littoral; Shallow water
Limnetic; Open water
Profundal; Below light layer
Ten different Biomes
Tropical Rainforest
Tropical Monsoon Forest
Savanna (tropical grassland)
Chaparral
Desert
Temperate Grassland (prairies)
Temperate Deciduous Forests
Temperate Rainforest
Taiga
Tundra
