trophic (feeding biology)
shared evolutionary histories, creating taxa such as vertebrate animals, insects, coniferous trees, & orchids.
carbon dioxide as a source of carbon & light as a source of energy to synthesize organic compounds
synthesize organic molecules using CO2 as a carbon source & inorganic chemicals, such as hydrogen sulfide as their source of energy
other feeders are organisms that use organic molecules both as source of carbon & as a source of energy
are prokaryotes distinguished from bacteria on the basis of structural, physiological & other biological features
photosynthesis autotrophs synthesize organic molecules using CO2 as a source of
carbon & light as an energy source
photosynthetically active radiation (PAR)
visible light carrying sufficient energy to drive the light-dependent reactions of photosynthesis, but not so much as to destroy organic molecules
separates carbon fixation & light-dependent reactions of photosynthesis into separate cells
in C4 plant, the acids produced during carbon fixation diffuse to specialized cells surrounding a structure
crassulacean acid metabolism is largely found in succulent plants in arid & semiarid environments & among epiphytes growing in the canopies of forests
chemosynthetic autotrophs synthesize organic molecules using CO2 as a
carbon source & inorganic molecules as an energy source
concerns the balance of multiple chemical elements in ecological interactions
predators select predators by size because they must catch & subdue their prey
can be measured as total, or gross, CO2 uptake during photosynthesis minus the CO2 produced by the pant's own respiration
gradually increase the amount of food available to a hungry animal, its rate of feeding increases & then levels off
general prediction is that predators will continue to add different types of prey to their diet until the rate of energy intake reaches a maximum
photosynthetic autotrophs synthesize organic molecules using
CO2 as a source of carbon & light as an energy source
chemosynthetic autotrophs synthesize organic molecules using
CO2 as a carbon source & inorganic molecules as an energy source
maples, bluegrass & wheat - carbon fixation in plants - midrange temperatures - less sensitive to cold temperatures
fix CO2 at night - reduce water loss for arid & stressful environments - Aloe & Pineapples
CO2 for carbon source, use chemicals for energy rather than sunlight - sulfur hydrogen sulfide ammonium nitrite iron hydrogen carbon monoxide
