Answer:
True
Explanation:
Because within the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria (also known as purple bacteria), heliobacteria, Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Chlorobi (green sulfur bacteria), and cyanobacteria.
 
        
                    
             
        
        
        
An invasive species will often become dominant in which case the diversity index would decrease. This happens when the invasive species pushes out other species as it takes over the area. If the invasive species is unable to adapt, the diversity index would likely not change. 
        
             
        
        
        
Answer & Explanation:
Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different. 
 
        
             
        
        
        
Answer: No
Explanation: Exotic and invasive species are two types of non-native species, which are introduced to ecosystems by natural processes or humans. Most exotic species are domestic, and they do not harm ecosystems. But, invasive species are harmful to the ecosystems.
