A placement of biomes throughout the earth as a result of climate , particularly temperature and precipitation

Ecosystem distribution

Explanation:

The placement of biomes throughout the earth as a result of climatic factors such as temperature and precipitation is referred to as ecosystem distribution.

Biomes generally represents a community of living organisms that are able to tolerate the climate of a place based on shared attributes. For example, all plants in the desert biomes are able to withstand low water.

An ecosystem refers a collection of different communities of organisms that are interacting with one another and their physical environment as a form of system.

Climatic factors such as temperature and precipitation delimits species distribution in an environment. Communities that are able to tolerate similar climatic conditions are placed in the same ecosystem. Hence, we have the forest ecosystem, desert ecosystem, marine ecosystem, freshwater ecosystem, etc.

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.
