Later, ecologist Arthur Tansley created a separate definition for ecosystems, which was more inclusive of biological processes than the definition of a biome. Over time scientists continued to expand and refine the definition of biome and related concepts in the burgeoning field of ecology, and in 1963, Shelford characterized the following biomes: tundra, coniferous forest, deciduous forest, grassland, and desert. In 1939, it was further defined by Clements and fellow ecologist Victor Shelford. Clements, an American ecologist, to describe the plants and animals in a given habitat. The term “biome” was first used in 1916 by Frederic E. Meanwhile, biomes describe life on a much larger scale than either habitats or ecosystems. A habitat, on the other hand, is specific to a population or species it is the area in which that group lives. Nutrient and energy flow also play a critical role in ecosystems. Ecosystems are the interactions between biota, such as plants and animals, within the environment, and many ecosystems can make up a single biome. Defining Biomes Biomes are sometimes confused with similar ecological concepts, such as habitats and ecosystems. However, not everyone agrees on exactly what constitutes a biome and defining them presents a challenge.
For instance, the plants and animals that inhabit the Amazon rainforest are completely distinct from those in the Arctic tundra. Each biome, or community of plants and animals in a certain climate, has life-forms characteristic of that place.
