2. Organisms are not distributed across Earth because the patterns of distribution are largely due to abiotic factors. Most organisms receive their energy from the sun, either directly or indirectly. Organisms require certain levels of abiotic conditions, which are things such as temperature, humidity, salinity (saltiness), moisture, etc. Organisms can tolerate fluctuation in these levels but only within a certain range – there is always a certain level that suits the organism best. Therefore, it is the abiotic factors that affect the distribution of Earth’s organisms.
