1. Kingdom Monera
Bacteria

2. Bacteria Prokaryotic, single celled micro-organisms Rod shaped
Cell wall
Most are heterotrophic
Heterotrophic bacteria or decomposers
Break down dead organic matter into smaller molecules

3. Ocean bottom. That’s where there food collects eventually.
Recyclers of the earth
Found everywhere
On surfaces
In the water column
Bottom sediment
Where do you think you would find the most bacteria and why?
Ocean bottom. That’s where there food collects eventually.

4. What would happen if there were no decomposers?

5. Autotrophic Bacteria 2 groups Photosynthetic Chemosynthetic
Chemosynthesis- the making of organic material from inorganic substances using chemical energy.

6. The chemicals in hydrothermal vent fluid would be toxic to most forms of life familiar to us.
These organisms depend on chemosynthesis, a process in which certain microbes use chemicals in the vent water to produce energy.
They in turn form the base for an entire food chain of animals.
Chemosynthetic microbes grow on and below the seafloor and even within other animals at the vents.

7. Do chemosynthetic bacteria contain chlorophyll? Why/why not?
Chlorophyll is the pigment used by green plants to capture the energy of sunlight.
Chemosynthetic bacteria use the energy stored in chemicals like hydrogen sulfide and ammonia.

8. Cyanobacteria-blue green algae
3rd group of bacteria
Plant-like group of photosynthetic bacteria
Not true algae b/c they are prokaryotes
Have green chlorophyll and bluish and red pigments
No chloroplasts!
Microscopic as individuals
Can form strands or mats

9. Found just about everywhere regardless of temperature and salinity!

10.
Red Tide
There can be tens of thousands of cyanobacteria in a single drop of water!
