Question

Q. Which of the following is/are example of proto-cooperation ?
a. Desulfovibrio and chromatium

b. The pompeii worm and sulphur oxidizing bacteria

c. Shrimp rimicans exocalata and filamentous sulfeur oxidizing bacteria

d. All of these ​

Answer 1

Answer:

Health professionals need to understand the important difference between gram-positive and gram-negative bacteria. Gram-positive bacteria are bacteria classified by the color they turn in the staining method. Hans Christian Gram developed the staining method in 1884. The staining method uses crystal violet dye which is retained by the thick peptidoglycan

Answer 2

An example of protocooperation is (a) Desulfovibrio and chromatium.

• Protocooperation is a sort of ecological interaction in which both the participating species gain from the relationship but it is not necessary for existence.
• In protocooperation, organisms only engage for the benefit they derive from the interaction.
• The relationship is frequently regarded as a form of mutualism (facultative mutualism).
• Although the relationship encourages growth and improves the odds of survival, it is not necessary for the species' overall survival and growth.
• Since all the species involved profit from the interaction, protocooperation is a form of mutualism.
• Protocooperation between desulfovibrio and chromatium serves as an association between the carbon and sulfur cycles.
