Warren is developing a model for tracking carbon atoms within an ecosystem and its environment. Warren knows that plants perform both photosynthesis
and cellular respiration. Does the number of plants in the ecosystem change
the effect of the ecosystem on carbon dioxide levels in the atmosphere?

b.have there own function.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.

well, since there is no answer choices, i will give an answer on how it works : )

the two objects are placed together. energy will always be transferred from the hotter object to the cooler object until they are equal. hope this is close to one of the answer choices : )
