Answer:
sample 1 because it's mostly made up of organic matter to help plant growth
Explanation:
Not (A) because a molcule with pH 7 is neutral eg, water
Not (B) because a molecule with pH >7 is basic/alkali which is the opposite of acid.
This leaves C and D.
Lets take one of the most commonly known acids, hydrochloric acid which has the formula HCl.
When acids are added to water they split up (dissociate).
HCl cannot split to give hydroxide ions but can give hydrogen atoms (which are actually hydrogen ions > H+)
so the answer is D
Consumers are living beings in a food chain that eat creatures from a particular species.
<span>Clumped dispersion is the most common type found in nature. The distance between neighboring individual is at a minimum. This is common among organisms that are usually preyed such as in herds or family groups. Evenly spaced distribution maximizes the distances between individuals. There is usually competition for a resource. Penguins are an example of this distribution. Random distribution or unpredictable spacing is the least common among the three. Each individual is independent of the other. They occur in environments that have consistent environmental resources and conditions. </span>
