I’ve got my final bio exam/formal assessment/gcse today and your channel has saved me. thank you so much :)

[khadijah]

All your videos have been so helpful for me to understand everything easily! I have my bio final exam tomorrow and this really helped alot!

[nevasimsek]

Could you please, please do one for nitrogen cycle ? thank you for this video though, it is very useful. :)

[liliamargret]

So helpful... now i finally understand the carbon cycle after 2 years

[annathebell]

Thank you so much. It’s confirmed that your gonna be very, very, successful. Thank you so much for teaching us for free and providing links to past papers. We are very, very thankful and grateful,

[scarlettalexaaa]

this helped me make some easy to understand notes! thankyou :)

[rainbowsquad]

Thanks for the vids I use these for my school work 👍🏻

[rokeyaelapreety]

a video on the nitrogen cycle, please!

[kokomin..]

THANK YOU SO MUCH MY TEST IS TOMORROW 😭😭😭😭

[makena_sw]

thanks this is really gonna help me in my bio exam and its so much more interesting than just reading notes

[halallettuce]

VERRY GOOD VIDS PLS KEEP UP AND DO THIS FOR OTHER SUBJECTS AND SCIENCES TNX

[annathebell]

thank you so much for this video! Very Berry helpful. Can u plz make a video on nitrogen cycle? It'll help a lot 😊 thank you!

[domdom]

Brilliant as per usual. Pictography is excellent.

[musisduck]

Thank you so much for helping me in my exams.
But can you make a video about the nitrogen cycle? It was added to the syllabus

[Colaris]

What if we run out of atoms?? Interesting to learn that whatever happens to carbon, it always gets released back at soon stage.

[sapphire]

amazing vid- could you do one on the rock cycle? sedimentary, igneous, metamorphic and all that jazz, id really appreciate it. thanks

[shirinshirin]

Your videos help so much. If you can make a video on the Nitrogen Cycle it would help me so much

@Cognito Do you think this would be a correct explanation for the C cycle, and should I correct or add something? “In photosynthesis plants absorb carbon in the form of CO2 from the air. This carbon is then transferred to the form of glucose, from which respiration can be done by the plant, hence returning C atoms back into the air as CO2, or the C atom in the glucose can be used to synthesise other C-atom-contacting molecules such as carbohydrates, lipids or proteins, and become part of the plant’s biomass. The plant my then be eaten. Thus C-atoms from the plant’s biomass are transferred to the animal: some of which will be returned to the air in CO2, some will become part of the animal’s biomass, and some will be lost in waste such as faeces, or the animal’s dead body. The plant/animal’s dead body will then be decomposed by decomposers, who will respire, using the C-atoms from the animal’s biomass, returning C-atoms back into the air for plants to photosynthesise with. However, some dead animal/plant biomass may be in conditions that don’t allow decomposition to occur, such as a lack of O2. Thus, the biomass and waste will over millions of years of high pressure and heat will become fossil fuels. They can be then combusted and hence the C-atoms would be returned to the air and the cycle will repeat.” Thanks!!!
