cellular respiration, volcanic eruptions, forest fires
three processes or events that add carbon dioxide to the atmosphere
Energy flows one way through an ecosystem, matter is recycled within ecosystems
How the flow of matter through an ecosystem differs from the flow of energy
When salt is dissolved in water, salt is the ___________
formation of fossil fuels
Geological process that reduces atmospheric carbon dioxide
Six major levels of organization
Species, population, community, ecosystem, biome, biosphere
Property of water that causes drops of water to form beads on a smooth surface
In a four-level energy pyramid, if the primary producers contain 60,000 calories of energy, the second-level consumer will contain _____________ calories.
net flux=(carbon in) - (carbon out)
net flux equation
A parenchyma cell with a thin cell wall, a large vacule, and develops many chloroplasts will most likely become a _____________ cell.
Light energy absorbed by pigments high-energy electrons that are used to convert NADP+ and ADP to the compound NADPH and ATP, trapping the energy in chemical form.
How light energy converted into chemical energy during photosynthesis
regulate stomata to prevent an excessive amount of water loss
The responses of plants to environmental stimuli such as light and gravity
Carrier of electron
It would decrease because the plant would be unable to take in carbon dioxide.
Suppose a plant's stomata close on a hot, dry day. How could this affect the plant's rate of photosynthesis?
Molecule that is recycled between the Calvin cycle and the light-dependent reactions during photosynthesis.
Not well because chlorophyll does not absorb much light in the yellow region of the visible spectrum.
How well would a plant grow under pure yellow light?
transpiration and capillary action
Which factors contribute to water movement through xylem?
6CO2 + 6H2O -> C6H12O6 + 6O2
equation for photosynthesis
One organism is harmed in parasitism and no organisms are harmed in commensalism
Difference between parasitism and commensalism
Secondary succession begins in soil and primary succession begins on newly exposed surfaces.
Primary difference between primary and secondary succession
Greenhouse effect, latitude, and transport of heat and moisture by winds and ocean currents.
Main factors that determine climate
Each has its own niche and survive by dividing resources
How do different species occupy the same habitat successfully?
Bees and other pollinators are known as...
First species to colonize a barren area
When the population increases rapidly with each generation
human disturbances, earthquakes, droughts
Examples of density-independent limiting factors
Limiting factors determine the carrying capacity of environments for populations.
How limiting factors affect the growth of populations
