What is the source of the carbon-14 that is used in radiocarbon dating in living organisms?
The source of carbon-14 used in radiocarbon dating in living organisms is cosmic rays from the sun interacting with nitrogen in the Earth's atmosphere, producing carbon-14.
Is carbon passed along the food chain?
Yes, carbon is passed along the food chain as organisms consume other organisms. When organisms eat, they obtain carbon-containing molecules from their food, which are used for energy and growth. When these organisms are consumed by others, the carbon is further passed along the food chain.
Why can't carbon dating be used on living organisms?
The process of carbon-14 absorption is still continuous.
How can an isotope like carbon be used to date dead organisms?
An isotope like carbon-14 can be used to date dead organisms by counting the atoms with a machine.
How does chemoheterotrophs obtain carbon?
Chemoheterotrophs obtain carbon by consuming organic compounds from their environment. They cannot produce their own food through photosynthesis and depend on other organisms for a source of carbon. This carbon is used in their metabolism to generate energy and build cellular components.
Are most organisms said to be carbon based?
All organisms on Earth are carbon based.
Where does carbon come from in an ecosystem?
Carbon in an ecosystem primarily comes from the atmosphere in the form of carbon dioxide. Plants absorb carbon dioxide during photosynthesis and incorporate carbon into their tissues. When organisms consume plants or other organisms, they obtain carbon for growth and metabolism. Carbon is cycled through the ecosystem as organisms respire, decompose, and are consumed by other organisms.
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.
What process in organisms is responsible for the release of carbon dioxide into the atmosphere?
The process responsible for the release of carbon dioxide into the atmosphere in organisms is cellular respiration. During cellular respiration, organisms break down glucose to release energy, which produces carbon dioxide as a byproduct.
Plants obtain the carbon used in the manufacture of organic compounds from?
Plants obtain the carbon they use to create organic compounds from carbon dioxide in the air during the process of photosynthesis. They absorb this carbon dioxide through small pores on their leaves called stomata. Through photosynthesis, plants convert carbon dioxide and water into glucose, which is used to produce other organic compounds essential for their growth.
What is the name of six carbon compound?
One example of a six-carbon compound is glucose, which is a simple sugar used for energy in living organisms.
What must all organisms be able to get rid of in order to survive?
Used oxygen (carbon dioxide) and used food (feces).
