Energy Flow and Nutrient Cycling in Autotrophs and Heterotrophs

[@jamiegallier2106]

Excellent presentation, as always. You make learning fun and interesting.

As a student of thermodynamics, it was a real eye-opener when I realized that 'life' is always found on entropy gradients. Simple plants intercept energy from sunlight before it hits the ground and its entropy would have risen dramatically as it would have been absorbed and turned into low-temperature thermal energy. Or in deep water thermal vents where higher temperatures dissipate on the ocean floor. To quote a movie, "life finds a way..." Thanks for another interesting and informative video.

Hey Professor Dave, In your studies of different scientific systems of energy & entropy, are there any interesting commonalities between multiple types of systems you have personally come across? For example - we can observe some rough commonalities between hydraulic circuits (pumps & pipes under pressure) and electrical circuits (voltage sources, resistances and cables) with how energy is transferred. We can even see some similar "systems phenomena" with structures, where loads, structural members and stiffnesses carry forces and strain energy. It seems the biosphere has similarities with energy transfer. I'm interested if you've come across a field of study exploring the universalities between different systems, and if you've found any interesting phenomena with how systems emerge in physical science? I don't know if my question is in the realm of the philosophy of science, and in how we choose to define and describe different systems, but I'd like your broad take on this topic as you have knowledge across a vast range of different systems.

Remember that you are based

You might wanna reread your posts before you post them. I think you meant “biased“. And if that’s the case, he’s definitely not biased.

The first part of this video focuses on photosynthesis and photoautotrophs. Why no mention of chemosynthesis and chemoautotrophs?

Decomposers and detritivores are different, even though detritivores are sometimes called "decomposers", as in a broader category, there are distinguishments made. "Basic difference- decomposers(fungi, bacteria ) "breakdown" the organic matter from the decaying organism whereas detritivores(earthworms, dung flies etc.) "consume" the large particles after they are brokedown by decomposers." "The terms detritivore and decomposer are often used interchangeably, but they describe different organisms. Detritivores are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter, allowing decomposers to perform the second stage of remineralization."

I think you said somewhere that you will make a video about Subboor? When will you make it?

[@ProfessorDaveExplains]

Yeah I will at some point, not super soon but fairly soon.

Excellent video, as always. Could you please make a video debunking alternate pseudoscientific treatments for cancer, misconceptions about cancer and chemotherapy? And also the distrust of western allopathic medicine and disbelief in the germ theory as a whole? Thanks a lot.

Sir please have a content in Statics, dynamics and many more Engineering courses please

Is math related to science and does it have to be put in a container?

Hey like your content! Can you make a video Flat Earth Banjo? He uses the bible and popular people to promote the flat earth.
