Species are assigned to tropic levels based on
Their main source of nutrition and energy
Primary producers synthesize organic molecules via the process of
Photosynthesis
Herbivores
Plants and primary producers
Primary consumers
Carnivores that eat herbivores
Secondary consumers
Carnivores that eat carnivores
Tertiary consumers
Organisms that get their energy from non living organic matter are
Detritivores
The amount of light energy converted to chemical energy in the form of organic compounds by autotrophs durning a given time period
Primary production
= to gross primary production - the energy used by the primary producers for their autotrophic respiration
Net primary production (npp)
Why is npp typically the key measurement of production?
It represents the storage of chemical emergent that will be available to consumers in the ecosystem
What units are used to express npp?
Energy per unit area per unit time
Biomass added per unit area per unit time
Where do we find especially high npp?
Estuaries and coral reefs
