Abiotic factors on the other hand, are non-living components of an ecosystem such as water, temperature, sunlight, nutrients, soil and the atmosphere itself. Lotic ecosystems can be contrasted with lentic ecosystems, which involve relatively still terrestrial waters such as lakes, ponds, and wetlands. These remote Inca ruins rival Machu Picchu.

Biotic factors This cookie is set by GDPR Cookie Consent plugin. These must be within certain ranges for the system to be habitable for living organisms. Cold water is denser than warm water, so it sinks to the bottom, where a fairly steady temperature is maintained. Draining of wetlands for development depletes habitats. There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). In total, nine environmental parameters were included: temperature, water depth, pH, oxygen .

Four major factors that affect freshwater are: Stormwater runoff due to increasing development as buildings, roads, parking lots, and other paved areas prevent the absorption of rainwater. What is the primary factor in freshwater ecosystems?
