Biomes are regions and as you travel from one region to the next, transitions take place slowly.
A biome can be defined as the an area that has specific types of trees in it. it has some of the defined animals and species that reside in that particular biome.
As we move from one biome to another biome that is similar has some of the characteristics similar to the previous one.
Example : temperate and tropical forest biome has similar characteristics.
No there exists a distinct physical boundary between the biomes separated by landmass and water bodies.
Explanation:Ecotone is referred to as a transition zone, between the two biomes. Where the two communities meet and integrate. It may be narrow or wide. Which means that they are separate either by forest land or by water or by the mountainous body. Thus they form a boundary with the natural or locally occurring species of the areas and ecotones have several complex variations in the planet that compete for the survival as beyond this competitive layer the dominance of adjacent community takes over, as a result, the ecotone represents a shift in dominance. At the time it may contain several adapted species over the time but generally, have clear cut and distinct conditions for hence lower species richness.
The answer is; TRUE
The transition between two biomes is called an ecotone. The ecotone may have the characteristic of the two biomes in which it borders. It may have plant species from both biomes. Examples of ecotones are the transition zones between grassland and forest biomes in equatorial mountain ecosystem.
