• D. Populations in all the biomes are similar.

Answer 1

The correct option is D Populations in all the biomes are similar.

Biomes are classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment. One type of biome can be present in different continents, for example the tropical rainforest are in South America, Africa, and Southeast Asia and this is because of the climatic condition of these region being similar.
An ecosystem is where communities of organisms rely on each other and their environment for their nutrition and survival. So even a single pond or large tree could have the biotic and abiotic components essential to form ecosystems by themselves. Populations are organisms of a species found in a given area. The flora and fauna of an area is majorly dependent on its climate and bear various adaptations to suit the same. For example, the polar bears are found in the arctic biome and the lions are found in the grassland biome.
