food web:the interconnected feeding relationships in an ecosystem. These relationships can be complex; some organisms may feed on more than one trophic level, or changes may occur depending on a species' life history stages or the availability of food.
<span>Proteins that are involved in the packaging of eukaryotic chromosome into "beads" called nucleosome are histones.</span>
A nucleosome is a segment of DNA wound in sequence around eight proteins called histones. Together the DNA and the histones form "beads"

Answer:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Explanation:
Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.
