The water must navigate through small holes in the aquifer rock, moving on average only a couple of inches each day. [16] The rate of groundwater recharge is the time it takes for groundwater to replenish itself and extremely slow, leading to water shortages, as humans remove water from aquifers faster than the rate of recharge.

Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe ) is any microscopic living organism or virus , which is invisibly small to the unaided human eye without magnification .
Naegleria fowleri, also known as the brain-eating amoeba, is a species of the genus Naegleria.It belongs to the phylum Percolozoa and is classified as an amoeboflagellate excavate, [1] an organism capable of behaving as both an amoeba and a flagellate.
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be ...
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. [16] The biota of an aquatic ecosystem contribute to its self-purification, most notably microorganisms, phytoplankton, higher plants, invertebrates, fish, bacteria, protists, aquatic fungi, and more.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
