An acid-base diagram for human plasma, showing the effects on the plasma pH when P CO 2 in mmHg or Standard Base Excess (SBE) occur in excess or are deficient in the plasma [23] Acid–base imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 [ 16 ] ).
The best-known homeostatic mechanisms in humans and other mammals are regulators that keep the composition of the extracellular fluid (or the "internal environment") constant, especially with regard to the temperature, pH, osmolality, and the concentrations of sodium, potassium, glucose, carbon dioxide, and oxygen.
Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...

A graminivore is a herbivorous animal that feeds primarily on grass, [1] specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing . These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose , which is abundant in fibrous plant matter and ...

An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3]Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
