The mass of living cells and tissues that has been assembled by organisms using solar energy.
What is trophic efficiency?
A measure of the amount of energy or biomass transferred from one tropic level to the net (higher) trophic level.
~10% of energy gets transferred.
What is bioaccumulation?
The process in which toxins (or other materials) are ingested by an organism at a rate greater than they are eliminated.
The monach eats milkweed as a caterpillar and when it is developed uses the poison to its advantage. It is a defense because it will kill the predators that eat it, but the toxins will not harm or affect the butterfly.
What is biomagnification?
A process in which the concentration of ingested toxinsincreases as it moves from one trophic level to the next.
Secondary consumers have to consume more primary consumers to fulfill their needs, that is how the mount of toxins are magnified.
What is cellular respiration?
A process that releases energy from organic molecules, especially carbohydrates, in the presence of oxygen. Occurs when oxygen is present or is under aerobic conditions.
What is fermentation?
A process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen (anaerobic).Organisms like bacteria and some fungi use fermentatoin to release the energy in glucose.
What are greenhouse gases?
Atmospheric gases that prevent heat from leaving the atmosphere, thus increasing the temperature of the atmosphere.
What is the greenhouse effect?
The warming of Earth as a result of greenhouse gases, which trap some of the energy that would otherwise leave Earth.
What is acid precipitation?
Rain, snow or fog tht is unnaturally acidic due to gases in the atmosphere that react with water to form acids.
