What are the three levels in the energy pyramid? How much gets lost each time?
Producers, Secondary and Primary. 90% gets lost each time.
How does a niche differ from a habitat?
A niche is it's job and a habitat is the enviroment around it.
Through what process does most water vapor enter the atmosphere?
Transpiration
What is meant by interconnectedness or interdependence?
All organisms are affected by the living and nonliving organisms.
What is ecology?
The study of reactions between organisms, living and non living components of the enviroment.
What is biodiversity?
The genetic # and variety of organisms in a given area during a specific period of time.
What are different ways a habitat can be altered?
By addding or taking away resources.
What are the four factors that can change a population size?
Birht Rate, Death Rate, Immigration and emmigration.
What are producers, consumers and decomposers?
Producers are autotrophs that capture sun energy to make organic molecules. Consumers eat other organisms to get their energy. Decomposers break down dead organisms to make nutrients.
What are biotic and abiotic factors?
Biotic factors are the living components of the enironment. Ex:Plants
Abiotic factors are the nonliving components of the environment.
Ex:Oxygen & Humidity
What is the difference between a food chain and a food web?
food chain is a single pathway.
Food webs show the interconnectedness between organisms.

Explain why the same area can support a greater # of herbivores than carnivores.
Because there has to be more energy to go up
Why is the aamount of sunlight important to the animals in an ecosystem?
The sunlight is where the energy is.,
What is acclimation? How does it differ from evolution?
Acclimation is an organisms adjustment to an abiotic factor. Evolution is how a species evolves or changes over a long period of time
How is a eukaryotic cell diffent from a prokaryotic cell?
It has a nucleus
What monomer makes up proteins?

Where does transcription take place in eukaryotic cells?
Within the nucleus
Which structure prepares proteins for secretion from the cell?
Golgi Apparatus
What is the role of the rough endoplasmic reticulum?
Producing Proteins
What provides energy for the calvin cycle:
ATP and NADPH
What is produced during the krebs cycle:
CARBON DIOXIDE and OXYGEN
Genetic information is contained in?
