Question

compare the following made by nutrition: (a) Saprotroph nutrition (b) parasite nutrition (c) autotroph nutrition​

Answer 1

Answer:

saprotroph- Depend dead and decay matter for their food

parasitic -Depend on other living organism for their food

autotroph-Synthesis their own food

Answer 2

$\huge\mathfrak\red{ANSWER}$

$\huge{NUTRITION........}$

➟Nutrition is the process of intake of nutrients from which organisms can derive energy for various life processes.

➟It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion.

$\huge\mathbb\green{SAPROTROPH \: NUTRITION:}$

➟Organisms derive their nutrition from dead and decaying organic matter.

➟They absorb nutrients through their body wall.

➟The organisms depend entirely on non-living substances as a source of food.

➟Bacteria and fungi are examples of organisms which follow saprophytic nutrition.

$\huge\mathbb\green{PARASITE\: NUTRITION:}$

➟Organisms depend on other living organisms for their nutrition.

➟ The organism on which the parasite feeds and derives its nutrition from is known as the host organism. The host organism is not benefited but is harmed in the association.

➟ Examples of parasitic organisms are several bacteria, fungi, plants (e.g. Cuscuta) and animals (e.g. tapeworm, Ascaris).

$\huge\mathbb\green{AUTOTROPH\: NUTRITION:}$

➟ Autotrophic nutrition means that simple inorganic substances are taken in and used to synthesise organic molecules.

➟ Energy is needed to achieve this. There are two types of autotrophs: photoautotrophs and chemoautotrophs.

➟ Photoautotrophs get their energy from sunlight and convert it into usable energy (sugar).

➟ This process is called photosynthesis. During the process of photosynthesis, not only is sunlight turned into energy, but carbon dioxide is taken from the air and oxygen is released in its place.

➟ Chemoautotrophs use inorganic energy sources such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia.
