10 What are the different types of heterotrophic nutrition?​

Answer 1

the different types of heterotrophic nutrition are:

1.Saprophytic Nutrition

2.Parasitic Nutrition

3. Holozoic Nutrition

Answer 2

Explanation:

7. (a)Breathing is just the inhalation and exhalation , In which diaphragm moves inwards and outwards

(b) No conversion of components takes place

Respiration

(a) It is the Conversion of H20 and Co2 in oxygen using adenosine triphosphate

8.} alveoli are designed in such a way that increases the surface area for the absorption or release of gas

9.} No ,plant will not remain healthy because the pathway for the exchange of gases is blocked which prevents respiration , hence plant will die after sometime

10.} Different types of heterotrophic nutrition are:--

A. Holozoic Nutrition

B. Symbiotic Nutrition

C. Saprophytic Nutrition

D. Parisitic Nutrition
