(Yes or No)

Decomposer?

(Yes or No)

Needs Oxygen to Survive? (Aerobic)

(Yes or No)

Desulfovibrio

Purple Sulfur Bacteria

Green Sulfur Bacteria

Cyanobacteria

Heterotrophic Bacteria

Answer 1

I'll give you some help, but this is a great way for you to learn about microorganisms.

Firstly, you know that autotrophs and heterotrophs use photosynthesis.

So if you know that, which ones in the table fall into that category? That answers your photosynthesis question.

What's another name for cyanobacteria? What do we know about that kind of algae

What do you know about purple and green sulfur bacteria? They don't need water as the reducing agent. What does that tell you about oxygen production?

Before you look at completing the table, write down some facts about each of the organisms. That'll guide you to the answers on the table.
