Due to increased amounts of dust, less sunlight reaches producers. Due to insufficient sunlight, the producers die. As the populations of producers decreases, the populations of the consumers will also decrease (food chain). As there are more dead organisms, there will be more decomposers (more proteins converted to ammonia) and hence, more nitrifying bacteria (which convert ammonia to nitrates). Hence, the correct option is B.Can anyone help me with this question 39 from 07 nov.

I read in a book that the plasmodium which causes Malaria can pass form the mother to the fetus via the placenta. But in one question, the mark scheme said that malaria cannot pass directly from parents to child?

fetus is not the same as the child.
The fetus is the unborn child, but a child is ... the born child?Excuse me?

I think they mean "child" as in the disease can pass through breastfeeding and not through the placenta...however I think the answer is b) malaria not because it's "correct" but because of elimination, i.e the other answers are incorrect. Also, they say "parent", not "mother", so sickle-cell is obv. incorrect as it require both parents to have the gene for sickle-cell..
Sickle cell anemia - genetic / hereditary and so can be passed from parent to child
TB / Cholera - bacterium and so can be transferred through the placenta? Not sure.
