What role does photosynthesis have in the cycling of matter into and out of organisms?

Explanation:

Photosynthesis has a role in the cycling of matter into

and out of organisms.

i) The cycling of matter in plants can be traced.

ii) The photosynthesis requires an energy input (sunlight) to occur. This

reaction requires, CO₂ and H₂O, and they combine to form sugar  

molecules and in return, release oxygen.

iii) Sugars produced by plants can be used immediately or stored for growth or for  

later use, they cycles continuously in and out of the plant

iv) They take  CO₂ and H₂O from outside and convert it into sugar and this sugar is used by other organisms and it cycles continuously.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
