Question

Distinguish between the following
1 Parasite and Saprophyte.
1 Autotrophs and heterotrophs.
​

Answer 1

The key difference between saprophytes and parasites is thatsaprophytic organisms obtain nutrients from dead and decaying organic matter while parasiticorganisms fulfill their nutritional requirements from another living organism.................

Answer 2

Answer:

Explanation:

Parasite and Saprophyte

Parasite

• It is defined as an organism that lives on another organism which is known as host either temporarily or permanently and uses the host as a source of food
• Eukaryotic organism
• Alive on host
• Harmful for the host and may lead to death
• Intracellular digestion
• Plasmodium and wasps

Saprophyte

• It is defined as an organism which feeds on the matter that is decomposing from the dead organisms
• Eukaryotic as well as prokaryotic organism
• Alive on the decomposing matter of dead organism
• Not harmful for the living organisms and helps environment
• Extracellular digestion
• Bacteria and fungi

Autotrophs and heterotrophs

Autotrophs

• Usually members of the plant kingdom and certain unicellular organisms like cyanobacteria
• Autotrophs are producers which prepare their own food.
• These can be classified as photoautotrophs and chemoautotrophs.
• The chloroplast helps in preparing food.
• They obtain energy from inorganic sources by converting light energy into chemical energy.
• Autotrophs can store light energy and chemical energy.

heterotrophs

• All members of the animal kingdom
• Heterotrophs are the consumers who depend on other sources for their food.
• These can be classified as photoheterotrophs and chemoheterotrophs.
• They do not contain chloroplast, so cannot prepare food.
• They obtain energy directly or indirectly from other organisms.
• Heterotrophs cannot store energy.
