Karenia brevis, the dinoflagellate responsible for red tides, is ____________ , meaning it can undergo photosynthesis when conditions are right, or it can ingest bacteria, algae, and animal waste if additional nitrogen is needed.
Mixotroph organisms are capable of obtaining energy from the environment by combining autotrophic and heterotrophic mechanisms. Karenia brevis is mixotroph.
What is mixotrophy?Mixotrophy is a nutritional strategy used by some organisms that combine autotrophy and heterotrophy to obtain energy. It is widely observed in aquatic environments and especially among phytoplanktonic flagellated algae.
The development of mixotrophy depends on the environment in which the organism lives, its limiting conditions, and resources availability.
This strategy is used in aquatic environments in which light and nutrients availability is scarce. So organisms can change from being autotrophs to heterotrophs, and vice-versa, according to the environmental pressures.
