Where do plants get the minerals they need?
There are 14 essential plant nutrients. Carbon and oxygen are obtained from the atmosphere, and the other nutrients are absorbed from the soil.
What is dating rocks?
Dating rocks is when the radioactive isotope, carbon-14 is used to determine the age of fossilised rocks. Carbon-14 is present in the air, and is absorbed by plants during photosynthesis. When animals/people eat plant matter, they absorb the carbon-14 from the plants into their bodies. It has a half-life of 5730 years and so the mass of C14 remaining in a fossilised rock can be used to determine the age of the rock.
What is exhaled by animals and absorbed by plants?
Animals, like humans, exhale carbon dioxide. Carbon dioxide is taken in by plants, and through the process of photosynthesis produce oxygen.
Where plants get carbon dioxide from?
from atmosphere
Why cant we use carbon-14 to date the rocks?
Carbon 14 is absorbed by living organisms. When they die, they stop absorbing carbon 14 and the isotope then decays. Form the time of death of the organism, the quantity of C14, as a proportion of the total carbon in the organism declines and, measuring that decrease allows the age (or time of death) of the organism to be determined.
When carbon atoms are part of living material are carbon-14 isotopes absorbed on a regular basis?
Yes, carbon-14 isotopes are constantly being absorbed by living organisms through the food they eat or the air they breathe. Once an organism dies, it no longer takes in carbon-14, and the isotope starts to decay at a known rate, allowing scientists to use it for radiocarbon dating.

What gas do plants absorbed from the atmosphere?
carbon dioxide
What is carbon and oxygen cycle?
It is the process which the carbon is absorbed by plants and converted it to oxygen
Do living organisms all have the same ratio of carbon- 14 to stable carbon in their bodies Why or why not?
yes but i am not sure why. i have the same question
What happens to carbon dioxide that is released by plants and animals?
The answer is: carbon dioxide that is released by animals is absorbed by plants ;)))
What do animals and man get carbon from?
Carbon exists as carbon dioxide in the atmosphere which is absorbed by plants during photosynthesis. All food chains start with plants so herbivores get carbon by eating plants and carnivores get carbon by eating herbivores.
How does the plants gets the substances it needs for photosynthesis?
Plants need only two substances for photosynthesis, water and carbon dioxide. Water is absorbed from the soil (or from the water if they are acquatic plants) and carbon dioxide is absorbed from the air (or again, from the water if the plants grow underwater).

How carbon cycles in earth systems?
Carbon cycles in earth\'s system when it is excreted by animals, and then absorbed by plants.

Animals, like humans, exhale carbon dioxide. Carbon dioxide is taken in by plants, and through the process of photosynthesis produce oxygen.
What is a heavy colorless gas in the air absorbed by plants to make food?
i think is the carbon dioxide
