Question

Cyanobacteria______.a.can fix nitrogen, thus causing many freshwater ecosystems to be limited by phosphorus availability.b.can mineralize phosphorus from wetland sediments, raising phosphorus levels in inland waters to the point of eutrophication.c.mineralize the phosphates in detergent from an organic corn into an inorganic form that can cause algal blooms and eutrophication.d.consume excess N and P in inland waters and so are essential tools for watershed restoration and management.e.occur when aquatic ecosystems are disrupted by invasive species, and can cause pathogenic infections of native species, further enhancing the invasive nature of introduced exotic invaders.

Answer 1

Cyanophtya

Step-by-step explanation:

Cyanobacteria also known as Cyanophyta are responsible for fixing nitogen and raising phosphorus level through mineralization they are also called blu-green-algae. They commonly obtain their energy from 'oxygenic' photosynthesis.
