EOC review #2. Carbon Cycle. Two Major Processes: Cellular Respiration: O2 + Glucose CO2 + H2O Photosynthesis: CO2 + H2O Glucose + O2. Nitrogen Cycle. Nitrogen is a major component in protein and DNA Found in water as -ammonia (excreted by aquatic animals)

Even the energy that Carnivores get from eating their prey can be traced back to a plant.
The shape of the pyramid implies there is “less” at the top. “Less” what and why is this necessary for success of the ecosystem? (Energy)Ecological Pyramids
The feeding( trophic ) levels and the flow of energy through an ecosystem.
Removing just one species can collapse a food web if it is the primary food source in a community with little biodiversity. If there is a lot of biodiversity then it will not have a large effect because the higher trophic levels will move to other food sources.
Only 10% !!!!!!!
The rest is excreted as waste or converted to heat through cellular respiration
Draw a diagram relating photosynthesis and cell respiration. Your diagram should demonstrate how and what atoms cycle through the system, how energy flows through the system and the cellular structures that perform each process.
On a biological level, how do we extract energy from the food that we eat?
T Your diagram should demonstrate how and what atoms cycle through the system, how energy flows through the system and the cellular structures that perform each process. hree forms energy takes as it passes through an ecosystem.
What two purposes does food serve our cells?
Why, when an organism dies, does the matter it is composed of disintegrate yet that (hopefully) doesn’t happen while we are alive?
The interdependence of two or more organisms on each other is called __________symbiosis________________.
AGAIN? This must be really important! Your diagram should demonstrate how and what atoms cycle through the system, how energy flows through the system and the cellular structures that perform each process.
A. a decrease in owlsB. an increase in hawks
C. an increase in mountain lions D. a decrease in raspberry bushes
If many trees are removed from a forest, what is the most immediate effect on the carbon cycle in that forest?
C. decreased combustion of fossil fuels
D. increased production of organic compounds
