Final Study Guide Part V Flashcards
Producers
Autotrophs
Make their own energy through photosynthesis and begin the flow of energy
Consumers
Eat the producers
Other consumers eat the herbivores and continue the flow of energy
Decomposers
Break down waste and dead plants and animals to provide nutrients for plants
Trophic levels
Producers Primary consumers Secondary consumers Tertiary consumers Decomposers
What happens to the amt of energy in each trophic level as it is passed from producers to tertiary consumers
As energy moves through the trophic levels, only 10% minutes s passed in each time
Mutualism
When both organisms benefit from their symbiotic relationship
Parasitism
When only one organism benefits from the relationship and the other is harmed
How is carbon cycled through the ecosystems of the earth?
In photosynthesis plants take CO2 from the atmosphere and use it to produce E
Respiration in plants and animals releases CO2
Combustion of fossil fuels
Path of light through a microscope
Light source—>condenser(iris diaphragm)—> sample—> objective lens—> ocular lens—> eye
Parts of a light microscope
Base, light source, iris diaphragm, coarse adjustment knob, fine adjustment knob, stage, stage clip, objective lens, arm, ocular lens
Relationship btw magnification and field of view
FOV is how much of a specimen can be seen at a given time. When magnification is increased the amt of the specimen that can be seen decreases
Difference btw qualitative and quantitative data
Qualitative data describes (data observed with our senses)
Quantitative data defines (measured by numbers)
How do we test for sugars (glucose)
Benedict’s
How do we test for starches?
Lugols iodine
How do we test for amino acids?
Ninhydrin
