Compare the similarities and differences between the three domains of life
nekit [7.7K]
<span>Similarities and Differences
     There are many similarities and differences between the three domains. Bacteria and Archaea differ in how they gain energy. Bacteria gain energy either by being phototrophs, lithotrophs or organotrophs. One similarity between domain Archaea and domain Bacteria is that they both contain only prokaryotes while domain Eukarya only contains eukaryotes. Domain Archaea is the only domain that is sensitive to antibiotics. Another similarity between domain Bacteria and domain Eukarya is that Methionine is the first amino acid seen during protein synthesis while in domain Archaea, the first amino acid is Formylmethionine. The last major similarity between domain Archaea and domain Bacteria is that they do not contain any organelles while domain Eukarya does. A difference between all three domains is what their cell walls contain. A cell wall in domain Archaea has peptidoglycan. The organisms that have a cell wall in domain Eukarya, will have a cell wall made up of polysaccharides.</span>

Antelopes and elephants feed on the same species of grasses and shrubs in a savanna and the fitness of each species is reduced w
34kurt

Interspecific competition occurs between antelopes and elephants.

The term "competition" refers to the process that takes place among many species as they fight for the same limited resources in order to maintain their own existence. This struggle over resources occurs among organisms because these species occupy niches that overlap, and as a result, they are compelled to use the same resources like food, water, and shelter.

Competition can be either interspecific or intraspecific. The term "interspecific competition" refers to a type of competition that occurs between various species that live in the same biological area and are dependent on the same source of food.

In the question, both antelopes and elephants feed on the same grass and shrub species. Therefore they compete amongst themselves as a result of which their fitness is reduced.
