Energy and matter are transferred through the trophic levels of the ecosystem. Energy is lost at each level, resulting in a pyramidal distribution of energy and fewer creatures at higher levels.
In an ecosystem, the transfer of matter and the flow of energy occurs through trophic levels. When one organism eats another, the biomass is transferred from one level to another. However, not all energy is transferred between levels and some energy is lost as heat or used for metabolic processes. This loss of energy means a decrease in biomass and the number of organisms at higher trophic levels.
This results in a pyramidal distribution of energy, with the greatest amount of energy going to primary producers and the least to tertiary consumers. In general, the transport of matter and the flow of energy across trophic levels determines the distribution and abundance of organisms in an ecosystem.

This similarity can be explained by Charles Darwin's Theory of Evolution. Humans and chimpanzees share a common ancestor wherein a number of million years ago, due to adaptation of their environment, human species branched out and eventually evolved into Homo sapiens.
Answer:
The correct answer would be common ancestry.
Common ancestry means that different species have been established from a single parent species or population.
Organisms which share more recent common ancestors tend to have more similarity as compared to the organisms which share an older ancestor.
Humans and chimpanzees also believed to evolved from a common ancestor around 6-7 million years ago.
It is the reason why humans and chimpanzees share around 96-99 percent of the DNA.
B. Food production
C.Bioremediation
D.Bioaccumulation
Incomplete dominance
Complete dominance
Recessive
When traits from the parents blend together to form a new trait in the offspring, it is called codominance.
When two alleles or genotypes (of both homozygotes) are expressed jointly in offspring, it is referred to as codominance (phenotype).
Two other types of genetic inheritance are codominance and incompletedominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.
Therefore, in terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person.

In a population that is in Hardy-Weinberg equilibrium, the frequency of the dominant allele (in this case, for orange flowers) is p and the frequency of the recessive allele (for yellow flowers) is q. 48% of the population is heterozygous for the flower color alleles in this plant species under Hardy-Weinberg equilibrium. In this particular flowering plant species, orange flower color shows simple dominance over yellow flower color.
Given that 16% of the population show yellow-flower phenotypes in a population that is in Hardy-Weinberg equilibrium, we can calculate the percent of the population that is heterozygous for the flower color alleles.
Step 1: Determine the frequency of the recessive allele (q)
Since 16% of the population has yellow flowers (recessive phenotype), the frequency of the recessive homozygous genotype (qq) is 0.16. To find the frequency of the recessive allele (q), we take the square root of 0.16, which is 0.4.
Step 2: Determine the frequency of the dominant allele (p)
Using the Hardy-Weinberg equilibrium equation, p + q = 1, we can calculate the frequency of the dominant allele (p). Since q = 0.4, then p = 1 - 0.4 = 0.6.
Step 3: Calculate the percentage of heterozygous individuals (2pq)
To find the frequency of the heterozygous genotype (2pq), we multiply 2 by the frequency of p and q: 2 x 0.6 x 0.4 = 0.48.
Therefore, 48% of the population is heterozygous for the flower color alleles in this plant species under Hardy-Weinberg equilibrium.
