+ A type of algae can live in a salt marsh or in a
mangrove habitat. Scientists discovered that
the mangrove variety has higher levels of
chlorophyll when compared to the salt marsh
variety. Based on this finding, which statement
describes the most likely outcome?
A. The mangrove habitat will have reduced
amounts of atmospheric carbon dioxide.
B. The salt marsh variety will photosynthesize
faster than the mangrove variety.
C. The mangrove variety will photosynthesize
faster than the salt marsh variety.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.

the answer is definitely 36.
