Question 1

What are decomposers and detritivores?

Answer 1

• break down organic matter through secreted enzymes and catabolize complex molecules to simpler forms

Question 2

Examples of decomposers

Answer 2

Bacillus and Aspergillus

Question 3

What is mutualism?

Answer 3

both participating microoganisms benefits from each other

Question 4

examples of microbes with mutualism

Answer 4

rhizobium- fix atmospheric nitrogen into a usable form for the plant

gut microbiome- helps in digestion and nutrient absorption

Question 5

Answer 5

• one organism benefits while the host neither nor benefits

nosocomial organisms

Question 6

one organisms benefited while the host is harmed

protozoa, giardia and lamblia

Question 7

what is predation?

Question 8

Answer 8

mutualistic association
between a fungus and an alga or
cyanobacterium.

Question 9

where can lichens be found?

Answer 9

organic matter dead trees and rocks

Question 10

how do the separate organisms from lichens benefit one another?

Answer 10

Fungus (ascomycete) benefit from organic matter produced by photosynthetic alga/cyanobacteria

Phototroph
-protected from harsh condition
- lichens acid dissolve nutrients
- water uptake

Question 11

Aside from fungus and alga, what is the third partner of lichens

Answer 11

• basidiomycete yeast
