Compare this fungus with the protist shown in the images below. How do they differ in the way they obtain nutrients? Question 22 options: Both organisms are autotrophs. The mushroom uses hyphae to get its nutrients and the amoeba uses the pseudopod instead. Both organisms are consumers. The amoeba engulfs its food with it;s pseudopod, while the fungus absorbs food from the dead leaves using its hyphae. The amoeba is a producer and obtains nutrients through photosynthesis; the fungus is a consumer and is decomposing leaf litter in the forest.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
