Document Summary
A community of different species interacting with one another and with their environment so as to perpetuate or sustain their grouping. Producers convert sunlight to energy and transform carbon dioxide to organic carbon and oxygen - autotrophs (self feeding) Consumers - heterotrophs must get carbon from other sources i) ii) iii) iv) Various microbes colonizing the gut of a termite. Shares many of the species and characteristics of both ecosystems. Yet unique conditions - characterized by greater biodiversity. Break down dead organic matter to its fundamental building blocks (ie. bacteria, insects, protozoa, fungi) Considers the total mass of all members of an ecosystems (producers and consumers) Higher levels in the pyramid = decrease in efficiency of energy conversion. Each level > trophic level > encompasses all those organisms in a food web. Start from original source > heat lost on way > highest trophic level. More realistic representation of feeding relationships in ecosystems.
