A student designs an investigation to evaluate the effect of water acidity on the growth rate of potted spruce trees. What should be the independent variable in
the student's investigation?

the answer is false?

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

what is the statement?

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
