The right answer is B
A primary producer corresponds, in an ecosystem, to an autotrophic living being, that is to say capable of producing organic matter from mineral matter. It is the first element of the food chain. This organism is totally or partially ingested by a primary consumer, itself being the potential target of secondary consumers.
Decomposers are living creatures that contribute to the degradation of dead organic matter or feces by returning them in mineral form. They play a crucial role in an ecosystem because they participate in the recycling of the elements.
B+ Bb Ww male × B+ Bb Ww female Because beardedness and coat color independently assort, we can treat them independently. The difference between this cross and a dihybrid cross is that the bearded allele B b is dominant in males and recessive in females. So we deal with male and female progeny separately. For each sex, then, we should get a typical dihybrid ratio. In males, the dominant phenotype is bearded, so we should get ¾ bearded, ¼ beardless. In females the dominant phenotype is beardless, so we should get ¾ beardless and ¼ bearded. Each sex will have ¾ black and ¼ white coats.

they’re the same thing
I think B sorry if I’m wrong
Requirements for folate increase by 50 % during pregnancy, Folate plays a vital role in the production of red blood cells and helps the fetus neural tube to develop into her brain and the spinal cord.
