Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Explanation:
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers

Answer:
8 amino acids differ between the monkey and the human sequences.
Explanation:
The genome mapping has now made it possible to identify genes that are present on a chromosome. Genetic mapping is also being used to study the similarities between organisms which has helped a lot to understand the evolutionary history among organisms and to assemble the phylogenetic lineages.
Scientists have found the genome of the monkeys to be the most similar to humans with a difference of just 8 amino acids between them. Hence, justifying the hypothesis that humans have evolved from monkeys.

DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
