Grand Lake. Rocky Mountain National ParkAt the edge of Rocky Mountain National Park, Grand Lake is the deepest natural lake in Colorado, dipping to 265 feet. Fed by high mountain runoff, the lake is clear and pristine. In the summer, you can rent a boat, bring your own or simply enjoy the gentle lapping of the waves from the sandy shore.
Document to print. The four fundamental ecological processes of ecosystems are the water cycle, biogeochemical (or nutrient) cycling, energy flow and community dynamics, i.e. how the composition and structure of an ecosystem changes following a disturbance (succession).
Most energy in ecosystems comes from the sun, entering as light, then being converted to chemical energy and ultimately leaving the ecosystem as heat energy.However, energy can exit the ecosystem as heat during any point in the process, which means that energy availability decreases along a continuum.Once energy enters an ecosystem, its transfer basically boils down to which species feed upon which other species.lants in an ecosystem are considered primary producers because they supply nearly all of the energy, or food, that other species need to survive. Plants -- including flowers, trees, seaweed, algae and much more -- sustain themselves not from other species in the ecosystem, but from mere sunlight.
