Biosphere
New organic material that has been produced in an ecosystem
Biomass
Parasites that live inside their host and parasites that remain outside their host
Ectoparasite and Endoparasite
Development of a community in an area that has not supported life previously and sequential replacement of species that follows disruption of an existing community
Primary and Secondary succession
The rate of births in a population
Growth Rate
Includes all of the organisms and the nonliving environment in a particular place
Ecosystem
Rate at which biomass acumulates
Net Primary Productivity
