When it comes to heterotropic nutrition in plant, does the quality and nature of soil in which they grow, influence their mode of nourishment? Give reason for your answer?
Answers
Explanation:
Heterotrophic nutrition is the mode of nutrition in which organisms depend upon other organisms for food to survive. All animals and non green plants are heterotrophic.
Heterotrophic organisms have to acquire and take in all the organic substances they need to survive.Heterotrophic nutrition and control of bacterial density]
All heterotrophs (except blood and gut parasites) have to convert solid food into soluble compounds capable of being absorbed (digestion).Then the soluble products of digestion for the organism are being broken down for the release of energy (respiration). All heterotrophs depend on autotrophs for their nutrition. Heterotrophic plants have only four types.
The four main types of heterotrophic nutrition are:
Holozoic nutrition: the word holozoic is made from two words- holo= whole and zoikos= animals and literally means animals which eat their food whole. Complex food is taken into a specialist digestive system and broken down into small pieces to be absorbed. This consists of 5 stages, ingestion, digestion, absorption, assimilation and egestion. E.g.: human
Saprobiontic/saprophytic nutrition: Organisms feed on dead organic remains of other organisms.
Parasitic nutrition: Organisms obtain food from other living organisms (the host), with the host receiving no benefit from the parasite.When a parasite is present inside the body of the host, it is known as an endoparasite. These parasites suck and feed on the blood of the host. E.g.: tapeworms
Symbiotic nutrition:Two organisms live in close association to benefit each other or one of the two benefits the other while it itself suffers neither loss but nor does it gain. E.g.: fungi and algae, rhizobium in the roots of leguminous plants, etc.
Answer:
Heterotrophic nutrition is a type of nutrition in which organisms depend upon other organisms for food to survive. Heterotrophic organisms have to take in all the organic substances they need to survive. No All animals, fungi, and non-photosynthesizing plants are heterotrophic. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight. Heterotrophic mode of nutrition is of three types: 1. Saprotrophic nutrition 2. Parasitic nutrition 3. Holozoic nutrition
