Question 5

What are the shapes of bacteria?

Answer 5

Cocci (spherical)
Rods
Spiral

Question 6

What are the types of autotrophs?

Answer 6

Photoautotrophs - use the energy of light during photosynthesis (e.g. cyanobacteria, found in natural waters)
Chemoautotrophs - get energy by oxidizing inorganic compounds during chemosynthesis (e.g. deep sea vent bacteria)

Question 7

What are the types of heterotrophs?

Answer 7

Parasites -
Decomposers (saprotrophs) - feed on dead material, provide nutrients for other organisms
Symbiotics - help plants to get enought nitrogen to build up their proteins (nitrogen fixing bacteria), other bacteria live in our bodies and they produce vitamins (Vitamin K and B)

What are pre-biotics?

Answer 8

Food for bacteria (substances that can only be metabolised by bacteria)

Question 9

Answer 9

Live bacteria (active bacterial cultures)

Question 10

Answer 10
