* What are the three tropic levels?
Producers are organism that captures energy from the sun or from chemical reactions to convert carbon dioxide to organic matter. Consumers in a ecosystem those organisms that derive their energy from feeding on other organisms or their products Decomposers organisms whose feeding action results in decay or rotting of organic material. The primary decomposers are fungi and bacteria.

* Give 2 examples of each tropic level that can be found in your town, city or county. We have a food chain and a food web. Food chain the transfer of energy and material through a series of organisms as each one is fed upon by the next. Food web the combination of all the feeding relationships that exist in an ecosystem. * What tropic level do you think is the most important in the ecosystem and why? In any ecology, there is a foundation, and that is the producers. Electromagnetic energy in the form of light is used to convert CO2 to chemical energy, in the form of biomass. This can then be used to sustain each successive level. At each level, however, there is less useful energy, as much of it is used up by the previous level. As a result, in most food webs producers have the largest numbers, and each successive level of consumer has fewer and fewer numbers. This does not mean, however, that the producers are the most important, per se, since each and every tropic level is entirely necessary for the web to function. Remove one, and the entire thing collapses. There really is no “Most Important”. * What is biodiversity? Is it important? Relate biodiversity to the tropic levels. Biodiversity is the variation of taxonomic life forms within a given ecosystem or a biome. It is the measure of health of the biological system to indicate the degree to which the species are diverse and the count of viable versus extinct species. Each level of consumption in a food chain is called a tropic level. More diversity means more members of each...
