Marat540 [252]
Amount of rainfall
I’m not sure if this is right but I think it is because all of the rest are major parts of ecosystems, and although rainfall is too, it’s more of a natural source that happens anywhere whereas the rest of the options may determine the ecosystem

Which statement is FALSE about spontaneous generation theory? Group of answer choices When microbes grew in Needham's flask of b
lbvjy [14]

Answer:

Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies.

Explanation:

As rightly stated in the options of this question, the theory of Spontaneous generation is a theory that life forms can be generated from non-living or inanimate objects. Several scientists including Needham, Redi, Pasteur contributed to this theory experimentally by either proving or disproving it. Their contribution are as follows:

- John Needham boiled a broth containing living matter but noticed cloudy appearance representing microbial growth. Hence, when microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms.

- Francesco Redi, on the contrary, disproved the theory by conducting an experiment using meat. Redi DISPROVED the theory by concluding that flies were responsible for appearance of maggots on the meat. Hence, the statement that "Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies" is FALSE.

- Loius Pasteur also disproved the theory of spontaneous generation by using swan-necked flasks. His swan-neck flask experiment demonstrated that spontaneous generation does not occur
