Research and identify which plants on earth are the most abundant in biomass and the ecosystem(s) in which these plants can be found. Discuss how varying carbon dioxide levels can affect the growth of plants, thus affecting the levels of biomass.

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
