The Phosphorus Cycle
How is phosphorus used by organisms?
Phosphorus is used to make
phospholipids which make up
the cell membrane. Nucleic
acids - DNA and RNA -
contain phosphate groups.
what is the water stored under ground called
aquifer
Where does the energy in a food chain come from
the sun
What are the three main roles in a food web?
producers,consumers,decomposers.
how do fossil fuels get released
combustion
what is SEDIMENTATION
Dead marine organisms can get compacted by sediment -
over thousands of years, this can form sedimentary rocks.
what is evaporation
When bodies of water are heated by the Sun’s energy, water
can evaporate, turning from a liquid to a gas /vapor.
what is a decomposer in the food chain
an organism, like bacteria, fungi, or invertebrates, that breaks down dead plant and animal matter
What are some types of consumers?
Herbivores, carnivores, omnivores
what is the key process of COMBUSTION
The burning of fossil fuels is known as combustion. This releases vast amounts of CO2 into the atmosphere.
what is surface runoff
surface runoff is precipitation (rain or snow melt) that flows over the land surface
what are the two processes that turn the water in the lake to clouds
evaportation and condesation
what is a consumer in the food chain
any organism that gets energy by eating other organisms (plants or animals) because they can't make their own food
How is energy transferred in a food web?
Through the consumption of one organism by another.
what is the key process of CELLULAR RESPIRATION
Animals and plants use aerobic cellular respiration to release energy for biological processes. This also releases CO2
what is WEATHERING
This is the physical and chemical breakdown of rocks. In
this cycle, weathering causes phosphate ions to be released.
what is the process after precipitation
surface runoff
what are the 4 parts of the food chain.
producers (plants).primary consumers (herbivores) secondary consumers. carnivores that eat herbivores. and decomposes. bacteria and fungi
How does a change in one part of the food web affect other parts?
It can have cascading effects on multiple other organisms
what is the key process of photosynthesis.
Plants and algae take in carbon dioxide and convert it into sugars using sunlight and water.
what are the 5 key processes of the The Phosphorus Cycle
WEATHERING, SURFACE RUNOFF & FERTILIZER RUNOFF,DECOMPOSITION, SEDIMENTATION,UPLIFT
what are the 5 key proccess of the water cycle
What is the role of a producer?
to create their own food from inorganic sources, forming the base of the entire food chain and providing the energy that flows to all other organisms
What would happen if a predator was removed from the food web?
The population of its prey might increase
What are 5 key processes in the carbon cycle
PHOTOSYNTHESIS,CELLULAR RESPIRATION,DECOMPOSITION,FOSSILIZATION, COMBUSTION.
