Why would a ecosystem that had a high species diversity be more productive and effective?
nydimaria [60]

Answer:

the higher the diversity, the higher the populations of all the

photosynthetic organisms

Explanation:

Diversity in plant allows random mating also known as panmixia. It allows plant have equal chances of being mated too by any among them creating variations in the population. It leads to less fixed gene, reduce genetic drift leading to an increases population as some lethal gene may be lost due to recombination of gene among individual plant.

Where there is no diversity some gene becomes fixed leading to perpetuation of some traits that may be harmful in a population but diversity allows for the generation of new gene and allele frequency within a population.

Answer:

Ribose

Explanation:

DNA is a large molecule, a type of nucleic acid which store and act as a genetic material of the cell. DNA molecule is formed by the repeating monomer units called nucleotides.

Each nucleotide is made up of three subunits as:

1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.

2. Phosphate group (PO₄³⁻)

3. Nitrogenous bases: adenine, guanine, adenine and cytosine.

Thus, ribose is the correct answer.
