Food Chains
Organisms on the lowest level of a food chain.
What are producers?
The amount of energy available to the producers in a food chain.
What is 100 percent?
The relationship where animals try to get the same resources at the same time.
What is competition?
The movement of water vapor into the air from plants.
What is transpiration?
The increase of toxins in organisms as you look higher on the food chain.
What is biological magnification?
Primary or first level consumers are always described as this type of eater.
What is herbivore?
The amount of energy available to the secondary consumers in a food chain.
What is 1 percent?
The relationship where one organism benefits and the other is unaffected.
What is commensalism?
The cycle that includes photosynthesis and cellular respiration.
What is the carbon cycle?
The type of population growth that is ever increasing.
What is exponential growth?
Second level consumers may have these two types of eating habit.
What are carnivore and omnivore?
The amount of energy available to tertiary consumers in a food chain.
What is .1 percent?
The relationship where one organism hunts and kills another for food energy.
What is predation?
The two cycles most affected by deforestation.
What are the water and carbon cycles?
The type of population growth that really represents what happens in an ecosystem.
What is logistic growth?
A better representation of the food relationships in an ecosystem than a food chain.
What is a food web?
The amount of energy transferred between trophic levels in a food chain.
What is 10 percent of the level below?
The relationship where both organisms benefit.
What is mutualism?
The cycle most affected by increased burning of fossil fuels.
What is the carbon cycle?
As energy moves through the trophic levels, this is the way most energy is lost.
What is heat?
The level that will have the fewest organisms in a food chain of four levels.
What is tertiary or third level consumer?
If the producers have 9000 kilocalories of energy, what is the amount available to the secondary consumers?
What is 90 kilocalories?
The relationship that includes parasitism, mutualism and commensalism.
What is symbiosis?
The cycle most dependent on bacteria.
What is the nitrogen cycle?
When an ecosystem reaches the maximum number of organisms it can support.
What is carrying capacity?
