Which combination of statements about ecosystem components is correct?
Abiotic components include air, water, and soil. 2. Producers are the first trophic level. 3. Decomposers are not part of the ecosystem.
Biotic components consist of producers, consumers, and decomposers. 2. The base of the pyramid represents consumers. 3. Productivity is solely based on herbivores.
Each ecosystem has abiotic and biotic components. 2. Net primary productivity (NPP) is the biomass available for consumption. 3. The apex of the pyramid represents primary producers.
Decomposers play a role in energy flow. 2. Gross primary productivity (GPP) is the same as net primary productivity (NPP). 3. Biotic components include only plants.
