Question

What is the difference between Autotrophic and heterotrophic cellular nutrition

Answer 1

Explanation:

• Autotrophs store chemical energy in carbohydrate food molecules they build themselves.
• Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.

Answer 2

Autotrophic Nutrition:

• The mode of nutrition in which the organism is capable of preparing their own food.
• In this type of nutritional process, the organism is independent of other organisms for food.
• This type of nutritional mode involves preparing food using carbon dioxide and water in the presence of sunlight through the process of photosynthesis.
• The organism employing this mode of nutrition are known as producers.
• This mode of nutrition is carried out by the plants and some blue-green algae and bacteria.

Heterotrophic Nutrition:

• The mode of nutrition in which the organism does not prepare their food themselves.
• In this type, the organism is dependent on other organisms for food as nourishment.
• No photosynthetic activity occurs
• The organisms employing this mode of nutrition are known as consumers.
• The heterotrophic mode of nutrition occurs in all animals, fungi and all other non-photosynthetic organisms.
