What are the differences between an autotroph, heterotroph, consumer, producer, detritivore, and saprotroph
Autotroph: Makes its own food and gets all of its energy from the abiotic environment
Heterotroph: Cannot make its own food, gets food from consuming other living organisms
Consumer: Anything that eats another living organism
Producer: Similar to an autotroph. Converts energy from the abiotic environment into energy that living organisms can use (usually it is a plant or bacteria)
Detritivore: Eats non living organic matter but digests it inside its body
Saprotroph: eats non living organic matter too but digests it outside its body
Autotroph: self-feeding organisms, they make their own carbon compounds from carbon dioxide and other substances
Heterotroph: does not make its own food and obtains its carbon from other organisms
Consumer: feed off of other organisms by ingestion
Producer: make their own food and obtain energy from chemicals or the sun
Detritivore: digest dead organic material internally to absorb the products
Saprotroph: digest dead organic materials externally and secrete nitrogen back into the environment for other organisms
How is the oxidation of methane significant to the carbon cycle?
Only a handful of organisms are capable of methanogenesis (or oxidation of methane). The production of methane is an important and widespread form of microbial metabolism. In many cases, it is the final step in decomposition of biomass and is responsible for significant amounts of natural gas accumulations.
What are some of the environmental consequences that are associated with an enhanced greenhouse effect?
-Rise in sea water levels
-Increase of frequency of extreme weather (tsunamis, hurricanes)
-Increase in mean global temperature
Describe the relationship of Atmospheric CO2 concentration and Ocean pH levels.
The ocean absorbs about 1/3 of all the carbon emissions. Since atmospheric carbon dioxide is increasing due to an increase in emissions caused by human activities, the ocean absorbs more and more. When carbon dioxide combines with water, it forms carbonic acid. This causes the pH of the ocean water to decrease and become acidic, thus threatening the survival of the organisms unable to thrive in such conditions
Living organisms can perform various energy conversions like....?
