Answer:
Advanced,
Decomposers, producers, consumers
Skin
Explanation:
Decomposers are primary energy source by decomposing matter, this energy is released to the soil for plants absorb it to manufacture their food through photosynthesis and these food are consumed by man who gains energy in the process.
Higher layers should have more complex features than lower layers.
Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).

Are bunchgrass because they form a kind of ecosystem within the prairie.
