Answer:
<h3>Molisch’s test is a chemical test which is used to check for the presence of carbohydrates in a given analyte. This test is named after Czech-Austrian botanist Hans Molisch, who is credited with its discovery. Molisch’s test involves the addition of Molisch’s reagent (a solution of ∝-naphthol in ethanol) to the analyte and the subsequent addition of a few drops of concentrated H2SO4 (sulphuric acid) to the mixture.</h3>
First, waste matter wouldn't decompose and add nutrients to the ground. then all the dead plants and animals would build up until all the nutrients had been taken from the ground because it couldn't be replenished. then the herbivores would starve followed by omnivores and carnivores. Everything would die out eventually.
You have to first make some observations and then ask a question. Then you make a hypothesis (or guess) what the answer is - do the experiment to see if you're right!
A is the answer. Hope that helped.
