Which zone is most likely to have insects and very little plant life?
julsineya [31]

Answer:

The right answer is D. The benthic zone

Explanation:

The limnetic and the littoral zone  all get a lot of sunlight so there are a lot of plant life. The pelagic zone hosts a variety of plant species so this cannot be the correct answer. That leaves us with the benthic zone.

Benthic meaning inhabiting bottom areas or substrates. Plant life at the bottom is very scarce but there are a lot of insect species.

In photosynthesis, carbon dioxide is reduced and h2o is oxidized. What type of chemical reaction is this?.
Vilka [71]

In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.

<h3 />

Explanation

Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.

Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.

The oxidation-reduction reaction in photosynthesis is:

6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)

<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
