The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae are primarily responsible
The designs of Pasteur and Redi’s experiments were different such that Pasteur was able to show spontaneous generation was false, but Redi was not and is denoted as option C.
<h3>What is an Experiment?</h3>
This can be defined as a procedure which includes series of methods done to accept or refute a hypothesis or to ascertain its authenticity. Spontaneous generation is a theory which states that living organisms could arise from non living matter.
Pasteur experimented with broth while Redi experimented with rotten meat and Pasteur was able to confirm the micro-organisms in the air which disproved the concept of spontaneous generation and thereby making option B the most appropriate choice.

Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
