What is a prokaryote that obtains both energy and carbon as it decompses dead organisms?
Prokaryotes that obtain energy and carbon as they decompose dead organisms are categorized as both heterotrophs and chemotrophs. This means they obtain their energy from more complex organic substances, and that they gain energy from electron donors.
Why is it important that decomposers such as bacteria release nutrients?
If nutrients are not released then life processes will cease and no new organisms will be formed. Bacteria feeds on carbon compounds to break down the dead organisms and release nutrients.
What is another name for nutrient cycles in ecosystems?
The dead organic matter are an example of nutrient cycle and can sometimes be buried under sediment, rendering the carbon unavailable to living organisms.
What are three organisms the break down dead organisms?
what are 3 organisms that break down dead organisms
Organisms that break down complex compounds and dead tissue?
Decomposers
What is the use of carbon 14?
It is used to determin the age of different organic materials, by measuring the amount of carbon-14 in a material, compared to the amount of carbon-12.
What is carbon 13?
Carbon 12 is the most common isotope of carbon. 99.8% of all natural carbon in the universe as we know it is carbon-12
What is the role of decomposers in the carbon cycle?
recycle nutrients from dead organisms or their wastes
When decompose break down the carbon molecules in dead organisms?
carbon
Can carbon be found in dead organisms?
Yes
When decomposers break down the molecules in dead organisms?
carbon
When decomposers break down the carbon-containing molecules in dead organisms?
carbon dioxide is released
What is the role of the carbon cycle?
recycle nutrients from dead organisms or their wastes
What does carbordating mean?
Do you mean carbon dating? Carbon dating is a process that scientists use to try to ascertain the age of an item by analyzing the amount of a radioactive carbon isotope that is present in the item. Generally this is used to date biological items. Like, really old trees and stuff. The percent of the radioactive isotope in the specimen is accumulated to normal levels as the thing was alive, after it is dead it stops absorbing new carbon and thus by measuring the ratio of isotopes that are decaying we can determine the age of the item. (using the half-life of the radioactive isotope)
Decomposers break down dead organisms and produce?
Decomposers break down dead organisms which produce carbon dioxide and nutrients. These nutrients are then used by other organisms such as plants.
When decomposers break down the carbon containing molecules in dead organisms?
Oxygen is released.
How does modern technology help decode the artifacts found in the dead sea scrolls?
Carbon dating (the measure of the isotope carbon 14) was used to estimate how old the scrolls were.
