WebMar 28, 2024 · The difference between NPP (Net primary production) and GPP (Gross primary production) is that NPP (Net primary production) is the energy fixed by autotroph and their respiration, whereas GPP (Gross primary production) is the total biological productivity of an ecosystem. Both of them are different in terms of dependency on … WebAbiotic factors of a biome are non-living things in the habitat. Some abiotic factors of the tundra are: 1.) Permafrost. Permafrost. A layer of subsoil, or the layer of subsoil directly under the surface that is permanently frozen. In other words, the ground is permanently frozen. Nothing is able to penetrate the permafrost.
