Assertion :- The mode of nutrition in which organisms made their food by their own is called autotrophic nutrition Reason :- The organisms which undergo autotrophic nutrition is called autotrops Ans :- ???
Answers
Answer:
Autotrophs (or Autotrophic Modes of Nutrition)
Those organisms that can make food themselves from simple substances like carbon dioxide and water are called autotrophs. Their mode of nutrition is referred to as autotrophic. They do this by the process of photosynthesis. All the green plants are called autotrophs.
Explanation:
This is due to the fact that the green plants make their own food from very simple substances like carbon dioxide and water that is present in the surroundings. They do this by the process of photosynthesis.
We can also say that the green plants have an autotrophic mode of nutrition. These green plants contain a green pigment called chlorophyll which further helps in making food by absorbing energy received from the sunlight. Majorly the green plants synthesize their own food – not only for themselves but also for the non-green plants, animals as well as human beings.
Complete Question:
Although a part of the question is missing, we might be referring to the following question:
(i) Assertion and Reason both statements are true and Reason is the correct explanation of Assertion.
(ii) Assertion and Reason both statements are true but Reason is not the correct explanation of Assertion.
(iii) Assertion statement is correct but the Reason statement is wrong.
(iv) Assertion statement is wrong but the Reason statement is correct.
Answer:
(i) Assertion (A) and Reason (R) both statements are true and Reason (R) is the correct explanation of Assertion (A).
Explanation:
- There exist fundamentally two modes of nutrition to be specific, autotrophic nutrition and heterotrophic nutrition.
- The living beings that follow the autotrophic mode of nutrition are known as autotrophs comparatively organisms which have a heterotrophic mode of nourishment are known as heterotrophs.
- The significant distinction between these two modes is the ability to incorporate natural mixtures containing energy-rich molecules from inorganic sources i.e. the ability to photosynthesize.
- As we know, autotrophic organisms or autotrophs can produce their food using inorganic sources like water, carbon dioxide, hydrogen sulphide sunlight etc. though heterotrophic organisms or heterotrophs can not.
- Green plants and green sulfur bacteria, and cyanobacteria or Blue Green algae that can produce their food are called autotrophs. The method by which plants make their own food is spelt as photosynthesis.
- It is vital to take note that these bacterias contrast with plants as they don't yield oxygen as a by-product of their metabolic response.
- It is for the most part in light of the fact that the electron donor utilized in such microorganisms is water yet synthetic mixtures like hydrogen sulfide.
- Autotrophic nutrition is possible because of the ability of photosynthesis and chemosynthesis.
Thus, option (i) Both Assertion and Reason are true and Reason is the correct explanation of Assertion is correct.
