Ecosystems are communities of organisms that interact with one another and with their physical environment, including sunlight, rainfall, and soil nutrients. Organisms within an ecosystem tend to interact with one another to great extent than do the organisms between ecosystems.
Within each ecosystem are habitats, which are defined as the place where a population of organisms lives.
By 1969 the five kingdom system to classify organisms was presented. These kingdoms are: animals, plantae, fungi, protista and monera.
