Which of the following set of organisms are producers in an ecosystem 1.shrimp, spirogyra 2.mussel, daphnia 3.oscillatoria, ulothrix 4. Euglena,bacteria
Answers
Answer:
In the ecosystem the producers are group number 4, because euglena and bacteria both are producers in the ecosystem.
Bacteria is generally a decomposer in the ecosystem yet it may classify as a producer too because it creates food like creation of photosynthetic bacteria using sunlight.
And euglena are also producers because they have been classified as those who produce their own food through photosynthesis.
Answer:
The answer is Oscillatoria, ulothrix.
Oscillatoria is a prokaryote living in freshwater habitats(like a bacteria) which is autotrophic. Hence they can photosynthesise. similarly, ulothrix is an algae. Most algae belong to kingdom plantae.
Almost all organisms in kingdom plantae are autotrophic. Hence this option is correct. As all the other options has at least one organism which is non autotrophic
