Question

discuss which is the most dynamic ecosystem in your view and why​

Answer 1

Answer:

i hope it helps, thank you

Explanation:

Kelp forests are highly dynamic ecosystems and many are now changing in response to human activities at local, regional, and global scales.

“Dynamic” yes; “regulatory” not in all cases. D because all ecosystems are very complex blendings of flora and fauna species in widely disparate numbers and widely disparate physical environments, which, being dynamic, are changing a lot usually. “Self regulatory” is not so certain. The dinos were not able to survive, finally, a large asteroid impact that ended them. Some of the red tides are not exactly self regulating, but rather a runaway process that results in lots of stuff dying off. There are all kinds of examples like this. So maybe “usually self regulating” conveys more truth than falsity.

Kelp forests are highly dynamic ecosystems and many are now changing in response to human activities at local, regional, and global scales. Observed and predicted changes include range contractions and habitat loss (Filbee-Dexter et al., 2016; Tanaka et al., 2012; Wernberg et al., 2016), range expansions with colonization of new habitat or species replacements (Bolton et al., 2012; Smale et al., 2015), and increasing establishment of invasive kelps (James et al., 2014). At the same time, similar changes occur in a variety of species that compete with, or consume, kelps (Stæhr et al., 2000; Vergés et al., 2014), adding to the complexity of net effects on the kelp forests. The ecological consequences include habitat loss (Wernberg et al., 2016), loss of important detrital resource subsidies (Krumhansl et al., 2014), reduced temporal stability of the forest structure (South et al., 2015), as well as the creation of novel communities (e.g., tropical herbivores on temperate reefs) (Vergés et al., 2014). Another possible consequence is a loss of genetic diversity in the kelp forests, which may in turn reduce their resilience to further change (Wernberg et al., 2018). These changes will likely have significant impacts on marine biodiversity and ecosystem functioning because kelps are foundation species for hundreds if not thousands of habitat-associated plants and animals, many of which are socioeconomically important (Bennett et al., 2016; Blamey & Bolton, 2017; Vásquez et al., 2014).

Unlike other threatened marine ecosystems, kelps do have a remarkable ability to regrow full canopies within short time spans (years) and there are examples of wide-scale kelp forest recovery occurring in the past. Although the diversity of responses to biological, chemical, and physical change both between species within regions and between regions within species makes it virtually impossible to generalize predictions about the future of kelp forests, it seems almost certain that many kelp forests a few decades from now will differ substantially from what they are today.
