According to the competitive exclusion principle, two species cannot continue to occupy the same A) habitat. B) niche. C) territ
levacccp [35]

Answer:

Niche

Explanation:

Niche basically is the lifelihood of a species that involves feeding on what, drinking from what....

If both species are competing for the same resources, they would compete until a certain species is eradicated. (think of it as 2 species of ants in 2 colonies that are close to each other, take the same leaves, prey and stuff. They would fight with each other in other until one colony is eradicated.) hence, unless a species and adapt and change its niche, both species would fight until one is eliminated. Thus, the principle states that 2 species cannot continue to occupy the same niche, not living environment.

Natasha2012 [34]

Answer

Macromolecules in human body

             The macromolecules found in human body are:

1. Carbohydrate,

2. Proteins

3. Lipids, and  

4. Nucleic acids.  

Elements they common share

             All these macromolecules have three elements in common which are:

1. Carbon

2. Hydrogen, and

3. Oxygen.  

                   These elements constitute about 95% of human body.

Difference in Chemical properties

                    Carbohydrate is composed of glucose monomers, which may have aldehyde functional group or ketone functional group. Protein is composed of monomers called amino acids. Each amino acid has carboxylic functional group, amino group, alkyl or aryl group and hydrogen atom. Lipid is composed of fatty acids and glycerol. While nucleic acid is composed of monomer called nucleotide. Each nucleotide is composed of pentose sugar, phosphate group and nitrogenous group. Due to the presence of different functional groups all these macromolecules have chemical properties different from each one
