Some statements regarding C2, C3, C4 and CAM plants

a.) For Sucrose synthesis after C2 C3 and C4 cycle having different procedure

b.) C4  cycle reduces occurrence of C2 which is thermodynamically very expensive and toxic by increasing the assimilation of CO2 at high temperature almost at 35⁰ C

c.) C4 plant is generally found in near to equator  and they are more abundant than C3 plant

d.) In Dark when stomata are closed and CO2 not assimilated in the CAM plants

If an increase in dicynodont species diversity (i.e., number of species) occurred soon after the Permian extinction, and if it occurred for the same general reason usually given for the increase in mammalian diversity following the Cretaceous extinction, then it should be attributed to

Bagworm moth caterpillars feed on evergreens and carry a silken case or bag around with them in which they eventually pupate. Adult female bagworm moths are larval in appearance; they lack the wings and other structures of the adult male and instead retain the appearance of a caterpillar even though they are sexually mature and can lay eggs within the bag. This is a good example of
