What is the difference between a first level a second level and a third level consumers?
When one is considering an eco system all organisms are divided into one of 5 category's. producer, primary (first) consumer, secondary consumer, tertiary consumer and in some ecosystems there is a forth level consumer. producers are plants and any animal which obtains it energy from a source other than another animal. (eg.. deep water animals) primary or first level consumers feed on the producers and get there energy from them. secondary consumers obtain there energy from eating the primary consumers. tertiary consumers obtain there energy from secondary consumers, and forth level consumers obtain there energy from tertiary consumers. but this always doesnt work as some animals eat both primary consumers and secodary, these organisms are placed with in these category on a case by case basis
Asked in Ecosystems
Do autotrophs or heterotrophs undergo respiration?
Yes, both autotrophs and heterotrophs go through cell respiration; they differ in the way that they obtain their energy. Autotrophs are able to make their own energy from a source such as sunlight, where as heterotrophs obtain their energy from sources that they consume, such as glucose. The only differ in how they first obtain the energy.
