Which ecosystem has the greatest amount of energy overall?

Because plants and animals die at all points in food chains, decomposers are found at all trophic levels in ecosystems. Ecologists use ecological pyramids to describe the energy flow among the trophic levels. The area at the bottom of the pyramid of energy represents the greatest amount of energy in an ecosystem.

What organism gets the least amount of energy?

It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.

arlik [135]

Answer:

Purebred can be described as organisms that result from true-breeding. True breeding occurs parents who have a homozygous genotype are crossed so that the offspring produced might be similar to them. The alleles of the desired genes will be the same in the parents which will breed and produce similar alleles in their offsprings.

However, the phenomenon of pure breeding limits the gene pool and genetic variety becomes limited by such methods.
