apes test Flashcards
carbon cycle
- plants/animals consume carbon dioxide
- then they release it through respiration or decomposition
- the carbon dioxide returns to the atmosphere
phosphorus cycle
- Weathering
- Absorption of phosphorus by plants
- Absorption of phosphorus by animals
- Return to the environment through decomposition
Water Cycle
- abundant and renewable
- 71% of earth covered by water
- oceans are the main reservoir
- freshwater is scarce
- most of freshwater is ice
- only 1% of water is readily available
Transpiration
: Evaporation in plants
- through leaves, stem, etc.
- both require heat to occur
- both distill water – pollutants are left behind
Condensation
: gas to liquid
- creates cloud formation in the atmosphere
Groundwater
: water stored under the ground (ex. Aquifiers)
- rainwater infultrates through soil
- often ends up in an ocean or river
- taken up by plants through soil
- humans use wells for irrigation
sink
when a reservoir stores more of a nutrient than it releases
source
reservoir releases more of a nutrient than it stores
carbon sinks
pull co2 from atmosphere and stores it as stable substances
resource partitioning
the division of limited resources among different species in order to reduce competition
(ex. 2 different birds live in the SAME oak tree ; except one eats acorns and the other eats insects in the bark)
primary producer in the aquatic food chain
phytoplankton
describe a terrestrial ecosystem that will have the highest net primary productivity?
Warm temperatures, high rainfall, consistent sunlight
biome found in shallow waters off the coastline and is earth’s most biologically diverse marine biome
coral reefs
describe the flow of energy in most terrestrial and near-surface marine ecosystems
producers use energy from the sun to make organic matter ; such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain
the energy available to consumers determined by (total energy transformed by photosynthesis - energy used by plants)
net primary productivity
