Examples of symbiotic relationships are- Predation (+, -), Parasitism (+, -), Mutualism (+, +) and commensalism (+, 0).... Thank you so much Sir for this wonderful series. Explained in most simple ways. Anyone who is just willing to learn can understand all the concepts...🙏

Mutualsim is both species are benefited but symbiotic is only one species benfit...?

[@aqudasfatma9545]

​@@rtr180rider8 sir has clearly mentioned that atleast one species should be benefited and for others the relationship may be positive, negative or neutral.

Your explanation to neutralism seems correct but there could be one more possibility in which both species are unaffected Like "Even if resources are limited but both the species have a limited requirement in which the combined requirement for both the species is less than the amount of resource available then also there will be no competition".

[@OOkulShiksha]

Symbiotic Relationship - It is a type of interaction in which at least one of the species is benefitted. Conditions --: ● (+,0) : Commensalism ● (+,+) : Mutualism ● (+,-) : Predation & Parasitism

[@OOkulShiksha]

Absolutely correct

[@siddhantmishra4191]

Very good sir

[@sbr6725]

Symbiotic : Mutualism + + Commensalism + 0 Predation + - Parasitism + - Neutralism mtlb ki dono side agr competition ho bhi rha hai to kisi ko kuchh khasa frk nhi pd rha hai Na hi fayda ho rha hai or nhi hi nuksaan ho rha hai. Hai na sir? Eg. Mai apne bagiche mai sbji bhi uga rhi hu or ghaas bhi. Yahan competition mera or cattles ka hai jo mere paas hai. Lekin yadi mai sbji le rhi hu or cattles ghaas le rhe hain tb koi problem nhi dono ka sahi bn rha hai pr yadi cattles sbji khana bhi wahan se shuru kr denge to meri vali side loss mai chli jaegi. Ye neutral nhi reh paega.

Test series lena hain ish book-Environment ka UPSC ke liye.Agar chapter wise mil jaye test series to aur accha. Netralism mein aap keh rahe ki resource supply unlimited hain to dono species mein competition nhi hoga but Resource supply kitna bhi unlimited ho competition aur jealousy to hoga he ki kaun kitna jyada resource lega kaun kitna jarururat se jyada resource lega misuse karne ka bhi competition ho jayega. Sayad hm galat ho sakte hain par av to aisa lag rha hain.

[@OOkulShiksha]

We don't have test series dear...Competition ho sakta hai...par kafi kam hoga....jaise example le lo....sunlight ka (solar energy), wo resource bahut jyada sufficient hai, to uske liye koi fight nhi hoti.

I didn't understood bioaccumulation and biomagnification. Can you please explain this again

[@OOkulShiksha]

Bioaccumulation takes place in a single organism over the span of its life, resulting in a higher concentration in older individuals whereas Biomagnification takes place as chemicals transfer from lower trophic levels to higher trophic levels within a food web, resulting in a higher concentration in apex predators.

sir, like we say that energy reduces as we go from lower trophic level to higher one, but on the other hand we also know that fats proteins and carbs give 9, 4, 4kcal respectively , and we also know that protein and fat content is more in non veg foods than vegetarian food . so how it is possible because if we go by this concept then upper level organisms provide more energy.

[@alpha_leo5054]

25:33 Sir, I beg to defer, because in nature the resources are limited, so, such scenarios of unlimited resources don't exist. What I can think of as an example of neutralism it that when a deer, while drinking water in a pond, is attacked by a crocodile. A lion nearby may save the deer by distracting the crocodile but would kill the deer later for itself. Here, deer got saved from crocodile for a while, a (+), but later got hunted by the same lion, a (-), the final outcome is (0) for deer. Similarly, for the lion, he could have stayed hungry or might have become a prey to the crocodile, a (-), but now that deer is free, the lion can have it, a (+), thus final outcome to the lion, a (0). I think we can view neutralism in this way, in the context of risk and reward.
