Give an example of an abiotic factor.
anything non-living.
At each trophic level, 90% of energy is lost. How is energy lost?
It is used up by day-to-day metabolism, heat, and other activities.
The main purpose of cellular respiration is ______.
To make ATP
What is glucose?
A simple sugar that can be broken down to make ATP.
Where does cellular respiration occur?
The mitochondria
Which of the following organic compounds is the main source of energy for living things?

carbohydrates
Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in equilibrium by the uprooting activities of the elephants. If the elephants are removed, the grasslands would be converted to forests or to scrublands. The newly growing forests support fewer species than the previous grasslands. Therefore, elephants can be defined as what type of species in this community?
Keystone Species
Where do autotrophs get the glucose needed for cellular respiration?
from photosynthesis
What is an organelle?
organized or special structures within a cell.
What would you NOT find inside of a prokaryotic cell, such as a bacterium?
nucleus, mitochondria, golgi, ER, chloroplast
If you needed a macromolecule that would store your genetic information, which one would you use?
Nucleic Acid
What would happen to the number of tertiary consumers in an ecosystem if you removed a large number of producers?
The number of tertiary consumers would DECREASE
What is the equation for photosynthesis?
6CO2 + 6H2O + sunlight ==> C6H12O6 + 6O2
What is a heterotroph?
An organism that must consumer another organism for energy.
Which important cell structure helps maintain homeostasis (a stable internal environment) of the cell by controlling the type and amount of substances that go in and out of the cell?
cell membrane
