Get Answers to all your Questions
(a) What is an ecosystem ?
(b) List any two natural ecosystems.
(c) We do not clean ponds or lakes, but an aquarium needs to be cleaned regularly. Why ?
Answers (1)
a) Ecosystem is a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment.
b) aquatic ecosystem and terrestrial ecosystem
c) Because ponds and lakes are natural ecosystems and they have decomposers as natural cleaners to decompose the wastes of all aquatic organisms. So it's not necessary to clean them by humans. But aquariums are man-made ecosystems. They don't have decomposers or natural cleaners. That's why the aquarium needs to be cleaned regularly.
