Chapter 29
29.3 How do nutrients cycle within and among ecosystems?
Nutrients cycles: pathways the nutrients take
Recervoir: major source site
Water cycle: pathway by which water travels
Aquifers: underground recervoir
Carbon cycle: pathway by which carbon moves
Fosil fuels: receivors for carbon
Nitrogen cycle: pathway by which nitrogen moves
Nitrogen fixation: process that combines nitrogen and hydrogen to form amomonia
Denitrifying bacteria: bacteria that breaks down nitrates releasing njtrogen to the atmosphere.
Phosphorous cycle: pathway by which phosphorous moves.
29.1
Ecosystems
energy
most energy is lost as heat in the enviorment as it moves from organism to organism
factors in envirment
abiotic
biotic
nutrients
the supply does not decrease or inrease, it has always been the same
29.2 How does energy flows throught ecosystems?
Producers
Producers are the first step on a the energy pyramid.
Consumers
Consumers are Animals
So looking at the big picture, consumers depend on producers.
The ones who directly acquire energy from producers are the primary consumers, then the secondary consumer acquires energy from the primary consumer and so on
Producers are plants & phytoplankton
The producers acquire energy by doing photosynthesis to then give energy to the consumers
29.4
Human Interaction
Fossil Fuels and chemicals
Burning fossil fuels creates a lot of nitrogen and sulfur oxides, which can days later fall to Earth as acid deposition, which can affect living things on Earth.
Many human activities increase the amount of Carbon Dioxide i the atmosphere, which in turn is causing Earth to warm.
Fertilizers with a lot of phosphorus and nitrogen disrupts their cycle, and contaminates water, affecting the populations of living things that live there.
