Question

suppose water hyacinth is introduced into a lake ecosystem in the southeastern united states where it was not previously located. which of the following best predicts how this will impact the ecosystem over time?

WATER HYACINTH (Eichhornia crassipes) is an exotic free-floating aquatic plant from the Amazon River basin in tropical South America. The dark green, shiny leaves have expanded hollow stems (petioles) that enhance its ability to float and can extend to 2 m above the water level. Below the water surface, there are root-like structures (rhizoids) which balance the plant and keep its aerial parts upright while taking up water and some nutrients. It reproduces through flowers and seeds (which can remain viable for up to 15 or more years) and has vegetative propagation by its stolons which are lateral extensions from the main plant which produce new plants which eventually leave the “mother plant”.

IMAPACTS OF WATER HYACINTH:

Eichhornia crassipes can form dense floating mats that cover large areas of water surface - thus excluding light, and air. This then affects animals (including fish) and plants that live and grow below the water surface; the area of a water hyacinth mat can double over several days when conditions of water and temperature are optimal;

The floating water hyacinth mats can have serious mechanical impacts on water supply systems, drainage canals, inflows to hydropower turbines, movement of ships and river flows;

Water hyacinth increases evapotranspiration well above that of open water (often over 3 times “open pan” evaporation) thus causing significant water loss to dams, reservoirs and wild waters;

The crowding of plants at edges of water bodies can prevent people’s access to the water for domestic use, fishing and transport, and can, at the same time, make the water unsuitable for human use;

The mats provide habitats for intermediate hosts of human diseases such as bilharzia-carrying water snails and larvae and pupae of malaria-spreading mosquitoes;

The floating plants and the mats they produce can also provide habitats for dangerous animals (snakes, crocodiles) and can support other aquatic plants that then form “floating islands” that can block water flows and damage machinery - such as hydropower turbines.

Answer 2

Water Hyacinth on Lake Ecosystem

Explanation:

• Water hyacinth additionally decrease natural biological variety,effect on local submerged plants,pounding,changed immersed plant community through the pushing endlessly and another modified animals communication by blocking access to the water or potentially dispensing with plants the animals depend upon for shelter and nesting
• Water hyacinths do deliver oxygen
• The greater part of this oxygen on planet Earth originates from small sea plants considered phytoplankton that live close to the water's surface and float with the flows
