10%, 90% of energy is transferred to the energy store of the environment as heat. some of the energy is also lost due to being trapped in uneaten body parts, faeces and excretory products
define carbon sink
caron sink is an area that stores carbon from the atmosphere for a long period of time. It stores more carbon than it releases.
What are the two natural carbon sinks
forest and ocean
carbon sink in forest
A large amount of carbon compounds is produced and stored in trees when they absorb atmospheric carbon dioxide during photosynthesis
what are the two processes that make oceans the largest carbon sinks in the world?
solubility and photosynthesis
why are carbon sinks important
they can reduce the amount of atmospheric carbon dioxide which is a major cause of climate change
