Answer:
Net Primary Production = Gross Primary Production - Respiration
Explanation:
- <u>Gross Primary Production (GPP)</u> = The total amount of chemical energy that is expressed as carbon biomass created by primary producers in unit time.
- <u>Respiration (R)</u> = A fraction of fixed amount of energy that is used by primary producers for the cellular respiration and maintenance of existing tissues.
- <u>Net Primary Production (NPP)</u> = The remaining amount of the fixed energy.
Therefore, the equation that shows the relationship between gross and net primary production is,
<em>Net Primary Production (NPP) = Gross Primary Production (GPP) - Respiration (R)</em>
Net primary production is the amount of energy that remains behind after the consumption of some fraction of energy in respiration from the gross primary production.
Entomology is the study of insects, some scientists travel to the far ends of the earth to discover new species of insects. for example, the new <span>“Singing” Psyllid Species Found in Taiwan. (souce: entomologytoday)
</span><span>herpetology is the study of reptiles and amphibians, scientists are still mapping out that category because theres much we still need to know about those cold-blooded animals for example theres a dangerous rumor that the suburban gardens are spreading a deadly disease in frogs (source: sciencedaily)
mammalogy is the study of mammals, this is where our species of 'homo sapiens' is included along with the marine mammals. scientists in this field are diving down into the depts to discover more about the ones in the oceans, currently theyre trying to save seal pups from the decreasing land-ice down in Antarctica (source: marinemammalcenter)</span>
Birds. Since birds can fly, they could get to the barren island and on their way, they could pick up seeds in their feathers and carry them to the barren island.
