The Regions of the distinctly different physical areas that has serve as the boundaries between the different communities are called as ecotone
An ecotone is the transition area between the two biological communities, where the two communities must meet and integrate. It may be the narrow or wide, and it may be the local ("the zone between a field and forest") or regional ("the transition between forest and grassland ecosystems").
The Ecotones are the areas of the steep transition between the ecological communities, the ecosystems, and/or ecological regions along with the environmental or other the gradient. Ecotones may occur at multiple spatial scales and the range from the natural ecotones between the ecosystems and biomes by the human-generated boundaries

Answer:
Changes in the basal levels that are on the bottom of the food chain.
Explanation:
Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.
Answer:
The principal functions of the gastrointestinal tract are to digest and absorb ingested nutrients, and to excrete waste products of digestion. Most nutrients are ingested in a form that is either too complex for absorption or insoluble, and therefore, indigestible or incapable of being digested.
