Loss of biodiversity matters because it affects the overall sustainability of organisms in an ecosystem. It also affects how badly an ecosystem will be affected after something, maybe a natural disaster, or maybe a disease, strikes the region. (For example, if a disease affects a certain species of organism, if there was a lot of biodiversity among individuals, some will have some kind of natural immunity to that disease and survive, passing on their favorable traits to the next generation. However, if everybody was the same and did not have the immunity to that disease, that entire population would eventually die out.) <- This is also the reason that lack of biodiversity will inhibit natural selection.
Hope that helped you.
Yes I suppose they must. if the ground and crops all froze we wouldn't have food and if there was no more air we could not breathe and if there was no more sun we would freeze and if there was no more water we would die.
Answer:
At each stage of the trophic levels, only 10% energy is transferred from one level to another.
Explanation:
In an ecosystem transfer of energy from one stage to another is very inefficient. From first stage to next stage only 10% energy is transferred to next trophic level. Rest 90% lost in environment.
This is known as LINDEMAN's TEN PERCENT LAW. Given by Raymond lindeman.Only 10% energy from one trophic level to next trophic level is transferred. Rest is used in respiration, breakdown etc.
First stage of trophic level has the highest energy and the last trophic level has the lowest amount of energy.
