Abram Balloga Lesson 4 Assignment 1 1. Describe the attributes of the Lake Cayuga ecosystem The Lake Cayuga ecosystem has a fairly standard makeup for a large temperate lake- soil, water, organisms, nutrients both organic and non. The Sun is the source of all energy to the system, as there are no hot springs or chemical vents. When the lake is not frozen, plants and algae become the primary producers, taking energy from the sun and building carbon-carbon molecules like glucose in which energy is stored. Included in this process is the harvesting of non organic materials and nutrients from the environment- minerals from the soil or just floating about. The primary consumers in this system are then herbivorous organisms like fresh water shrimp and water beetles. Here energy is transferred through the changing hands of organic compounds, and meanwhile energy is spent and lost to the environment in the form of heat. Secondary consumers would include fish and otters, with larger and more aggressive species (pike) making tertiary and quadiary consumers. Then there are bacterial decomposers who will eat and remove all remaining organic nutrients from dead organisms. What is left is only non organic nutrients
