Bio20 Chapter 1 - Energy Transfer in the Biosphere
Terms in this set (17)
The process in which the mitochondria, in cells of plants, animals and other multicellular organisms break down carbs and other energy-rich products derived from them, such as fats, to generate molecules of ATP (energy made in the mitochondria).
The process by which plants, algae, and some kinds of bacteria use the Sun's light energy to chemically convert carbon (inorganic) into carbs (organic) such as sugars and starches.
Organisms that synthesizes its own food from inorganic molecules by using light or chemical energy; also known as autotroph.
An organism that cannot synthesize its own food through photosynthesis or chemosynthesis, and must derive some of its nutrients from organic molecules formed by producers (autotroph) also known as heterotrophy
Percentage of incoming solar radiation reflected by a surface
The process by which certain fungi and bacteria use the energy from chemical nutrients to chemically convert carbon (inorganic) into carbohydrates (organic) such as sugars and starches in the absence of light.
Organism that obtains energy by eating plants; also known as a herbivore.
Organism that eats primary consumers
Organism that eats secondary consumers
Organism, usually bacterium, fungus, earthworm, or insect, that obtains energy by consuming dead plant and animal matter or waste.
In an ecosystem, a feeding level through which energy and matter are transferred; indicates an organism's position in the food chain and it's determined by the number of energy transfer steps required to reach each level.
Model showing the linear pathways through which food (energy) Is transferred from producers to primary consumers and to higher trophic levels.
model of food (energy) transfer in an ecosystem that shows the connections among food chains
Pyramid of numbers
schematic representation of the relative numbers of organisms at each trophic level.
total dry mass of all the living, or once-living, organisms in a given population, area, or other unit being measured.
Pyramid of biomass
schematic representation of the relative amount of biomass at each trophic level.
Pyramid of energy
schematic representation of the relative amount of energy at each trophic level.
