When we trace energy through a food chain, about 90% is lost at each level and only 10% is preserved. But DDT, PCBs, and some other chemicals are subject to “biological magnification” where their concentrations increase dramatically at each trophic level. Explain why this is not contradictory.
thank u for all ur help!
While creationists would disagree, I believe humans were propelled to our current position in the food chain by the challenges we faced: Predators/prey inspired and developed our speed, stealth, cooperation, and cunning as a defense and a survival skill, as well serving to weed out the weak or infirm, ensuring that each new generation was stronger, and more apt to succeed. The same could be said for plagues, famines, conflicts, and any other challenge we’ve faced as a species – that they have been the fire in which our status as “dominant species” was forged.
Now, we consistently undermine the elements that would strengthen us further. Disease and famine are combated the world over, wars are treated with disdain, the unmotivated or incapable are fostered by the state and breed new generations of the same, and the only predators that remain to hone us are ourselves.
By eliminating most of what drives a creature to improve, how long before we start backpedaling into extinction?
While I support each person’s right to subscribe to whatever views they prefer to give comfort and meaning to their lives, I’d prefer to hear less about the afterlife and more about the question at hand, and how it effects the life/lives before us and our children and our children’s children. When and if the apocalypse ever gets around to coming, or I find myself roasting in a fiery hell, then I’ll be willing to consider such other points as relevant.
Would`nt it be a good thing if they became extinct? They are top of the food chain, so without them there would be more fish for fishermen to catch. Also it would be safer for swimmers. I cant think of any way that their existance benefits mankind.
India has tremendous potential to become the primary source of agricultural products, more specifically food products in the world. It has about 53% of arable land – land available for cultivation of crops as compared to a measly average of about 11% for the rest of the world. It has some feathers in it’s cap as the second highest fruit and vegetable producer in the world, 6th largest producer of fish and such like but still doesn’t make up to the top 10 food exporting countries.If it weren’t for some severe infrastructure and technology issues, there is actually stopping for this gigantic food bowl. With large tracts of arable land, inexpensive labour and high-quality produce tumbling out of the barns, there is a potential so huge that sometimes, the scope and scale is almost unbelievable.
However, if one had to point out at one single single reason as to why the Indian agricultural industry is such a laggard when pitted against the global standards, it could be the pathetic state of the logistics, distribution and and an inefficient supply chain. India faces an acute problem of large amounts of food wasted away due to the lack of a proper cold storage, cold chain and frozen food distribution system. If only this was in place, huge amounts of food could have been processed into some kind of value added foods and sold both locally and abroad.Annually, there is usually a large amount of such agricultural produce that is waste away. If there were cold storage systems, efficient cold chain, logistics and distribution companies, it could have been possible to process these primary products into newer, secondary products and resold to consumers locally and internationally. A strategy needs to be carved out for the growth of this industry and a lot of investment action is yet to see some real action.
Investment in cold storage, cold chain distribution, installation of food processing plants across the country, applied research on harvesting technologies an a rapid development of the food retail industry are all necessary steps that would ensure an organic growth in this sector.
What is Cold Chain?
A cold chain is basically a logistics system, which helps in maintaining and providing a series of facilities for ensuring ideal storage conditions for the persihables from the point of origin to the point of sale. A well developed and efficiently organized cold chain reduces wastage, spoilage and helps keeps the perishables intact thereby helping to maintain the quality of the harvested food products ultimately making the whole system cost effective to the farmers and that which ensures top-notch quality to the end user.

I have done a lot of thinking, and allergies are the only thing I can think of that don’t serve a purpose in life. Mosquitoes are part of the food chain, viruses curb the population. Even mental illness seems exists to remind us of how bad things could be. But allergies do not seem to make sense.
