Answer:
Carbon dioxide from the air is used to produce food for plant growth. Carbon moves from plants to animals when animals eat the plants. Also, Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. 
The burning of fossil fuels also releases carbon dioxide into the atmosphere.
 
        
                    
             
        
        
        
Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.
Explanation:
Geological time starts with Precambrian time.
Geologically, time is divided between the Precambrian era and present time into era.
The three eras are Paleozoic era, Triassic period and Cenozoic era.
Era is further divided into periods.
Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.
Geologic scale is the record of events in earth's history and evolution.
 
        
             
        
        
        
Plantlike and methanogen organisms share som similar characteristics, for instance, can both produce their own and can process their made food into energy for different cellular processes such as cell division, repair and maintenance. 
Despite this similarity though, the difference lies with the source of energy that get to produce the food. Plantlike organisms use sunlight and UV rays to photosynthesize. Whereas, methanogens use methane where sunlight is not present.
