Explain the ecological roles of prokaryotes: decomposers, producers, nitrogen fixers, pathogens, and various symbioses and recognize that cyanobacteria are the only group that has evolved the ability to carry out oxygen-producing photosynthesis

The ecological role of prokaryotes is : fixing nitrogen to be used by producers, producing organic carbon of the atmospheric oxygen.

Explanation:

1. Decomposers:  Organisms that break down dead organisms as well as waste products  to unlock the supplies of carbon, nitrogen and other elements. Releasing CO₂, breaking downg carbon into minerals to be released back into the environment.

2. Producers: Converting CO₂ into O₂, main food source of life.

3. Nitrogen fixers: Prokaryotes that converts atmospheric N₂ into usable compounds (nitrates, ammonium) for plants to be able to metabolize.

4. Pathogens: Can be diseases that affect certain species and change the environment.

5. Various symbioses:

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
