Modes Of Nutrition

Question 1

Name the types of Autotrophes

Answer 1

Photoautotrophs
Chemiautotrophs

Question 2

Define autotrophic

Answer 2

Uses simple organic materials to manufacture complex organic compounds

Question 3

Define photoautotrophs

Answer 3

Use light energy to convert simple organic materials to manufacture complex organic compounds

Question 4

Define chemiautotroph

Answer 4

Use the energy derived from oxidation to convert simple organic materials to manufacture complex organic compounds

Question 5

Define heterotrophic

Answer 5

Comsumes complex organic food material

Question 6

Briefly explain holozoic feeding

Answer 6

Takes food into their bodies and breaks it down
Ingests-> digests -> absorbs -> assimilates -> egests

Question 7

Name the types of heterorophic nutrition

Answer 7

Holozoic
Parasitic
Saprotrophic
Fungal feeding
Unicellular organisms

Question 8

Define parasitism

Answer 8

Feeds of host and causes harm
(Lives on/in host and is highly specialised)

Question 9

Define saprotrophic

Answer 9

Feeds on dead/decaying matter
Secretes enzymes onto food externally
Absorbes solvable products by diffusion

Question 10

Describe fungal feeding

Answer 10

Secretes enzymes from tip of hyphae
Digestion takes place outside of fungi
Growing top of hyphae penetrator food, secreting enzymes
Products absorbed by F.D. or A.T.
