Suppose some natural disaster occurs in the species of cement is forced to read locate from its original island where it dined on cactus flowers to an adjacent island with many freer cacti but an overabundance of orchids. what would be the immediate consequences to the species in the first month of change? a) the species would change it’s eating habit that to feed on orchids. b) all of the members of the species would make do with the existing cacti on their new island. c) the entire species would be extinct. d) most of the members of the species would die but somewhat survive.

most of the members of the species would die but somewhat survive

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
