Aquatic Plant
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Flora Of Ghana
The wildlife of Ghana is composed of its biodiversity of flora and fauna. Biodiversity Fungi Ghana is home to a significant number of fungi species including: ''Aspergillus flavus''; ''Athelia rolfsii''; ''Auricularia auricula-judae''; ''Curvularia''; ''Fusarium oxysporum''; ''Fusarium solani'' f.sp. ''pisi''; '' Gibberella intricans''; ''Gibberella stilboides''; and ''Macrophomina phaseolina''. The true total number of fungal species occurring in Ghana is in the thousands and given the generally accepted estimate that only about 7 percent of all fungi worldwide have so far been discovered and that the amount of available information is still very small. Flora The flora of Ghana is diverse with both indigenous and introduced floral species considered in Ghana's floral diversity. A total of some 3,600 species of the major regional centres of endemism represent the three major taxonomic groups. Floral diversity is more pronounced among the angiosperms represented with well over ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flora Of Mali
The wildlife of Mali, composed of its flora and fauna, is widely varying from the Saharan desert zone (covering about 33% of the country) to the Sahelian east–west zone, to Mali, a landlocked francophone country in North Africa; large swathes of Mali remain unpopulated but has three sub-equal vegetation zones; the country has Sahara Desert in the north, the Niger River Basin at its center and the Senegal River on the south.
