<span>As various other researchers, Ecologists, regularly utilize
models to help comprehend complex issues. Ecological systems are frequently
demonstrated utilizing PC simulation. PC simulations can consolidate a wide
range of factors and their effects. This is one reason they are valuable for modeling
ecology. PC simulations are likewise working models, so they can demonstrate
what may occur in ecosystem after some time. For instance, simulations of
global warming have been utilized to make expectations about future
atmospheres. And field study is the key element to investigate ecological
systems based on which at times are prepared the computer simulations.</span>
I think its D. but I'm not sure The reason being is it's a prosses that doesn't require the "help" or "cooperation" of other cells and it only effects the one cell.
