A canal is built connecting a freshwater ecosystem to the ocean. What types of species in the wetland would be most negatively affected by this change?

A) Species that require low salinity.

B) Species that can tolerate various amounts of salinity.

C) Species that require high salinity.

D) All species would be affected equally.

A.

Explanation:

When freshwater is met with the ocean salt is diluted to the freshwater. Therefore organism that require little salt would be put at a threat.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
