4.2 Flashcards
Nitrogen Fixation
atmosphere to amonia/amonuim
Nitrification
amonia/amonium to nitrites/nitrates
denitrification
nitrates/nitrites to atomsphere
inputs and outputs of photosynthesis
inputs-CO2 and water
outputs-oxegen and sugar
inputs and outputs of cellular respiration
inputs-oxegen and glucose
ouputs-CO2, water, energy (ATP)
cellular respiration
organisms use oxegen for energy use by animals, plants, fungi, ect
photosynthesis
plants trasform sunlight into energy
how do humans affect the carbon and nitrogen cycles?
burning fossil fuels, fertilizers, deforestation
carbon cycle
how carbon travels from the atmosphere to organisms to the earth and back to the atmosphere
nitrogen cycle
how nitrogen cycles through the atmosphere, organisms, the soil and back to the atmosphere
energy cycle
shows interactions between energy sources and the enviorment
How does BTB (a pH indicator) work?
It shows level of acidity.
differences between carbon and energy cycles
Energy flows through an ecosystem, while matter cycles within it. they both fdecrease as trophic levels go up.
how does a ph indicator change colors based on factors such as plants, animals and light?
It shows that when plants do not have light for phtosynthesis they break down glucose and release CO2 to preform photosythesis
