in both terrestrial and aquatic environments the ecosystems include communities made up of avariety of species
within both terrestrial and aquatic communities there are populations at thedifferent trophic(nutrient)levels
Differences betweenTerrestrial and Aquatic systems
because aquatic environments are so rich in nutrientsthey support more livethan equivalent terrestrial ecosystems. The small drifting photosynthetic organisms of the oceans, referred to collectively as phytoplankton are regarded as the major photosynthesizers, orprimary producers, of the earth,
aquatic environments aremuch more stablethan terrestrial environments, with smaller fluctuations in temperature and other variables,
