Francesco redi what year did he make his main discovery

Francesco Redi was an Italian scientist, physician, academician and poet. He was the first person to prove that spontaneous generation did not cause the growth of maggots in decaying meat, but they appeared from eggs deposited by flies.

Hi , the answer is 1668 , he designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars.

Correct B). Energy is lost at each level as heat, which increases randomization

Organisms which are placed in a different trophic levels holds different levels in the food chain. They must get a sufficient amount of energy in order to survive and reproduce.  About 90 percent of the energy an organism received from the lower trophic level is known to be used in the life processes.

It is known that there is a decrease in the amount of energy as it moves from one trophic level to another trophic level because energy is lost as a metabolic heat. Only 10% of energy is available for the next highest trophic level.

Hence, the correct answer would be option B.
