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.

IrinaK [193]
The answer is that Both aid in the expansion and relaxation of lungs. Diaphragm and the rib muscles are vital in the breathing process. During inhalation the intercostal muscles contract, expanding the ribcage, the diaphragm contracts, pulling downwards to increase the volume of the chest, pressure inside the chest is lowered and air is sucked into the lungs. During exhalation the intercostal muscles relax, the ribcage drops inward and downwards, the diaphragm relaxes, moving back upwards, decreasing the volume of the chest, the pressure inside the chest increases and air is forced out.
