(a) (i) Why does a kitchen garden called an artificial ecosystem while a forest is considered to be a natural ecosystem ?
(ii) While designing an artificial ecosystem at home, write any two things to be kept in mind to convert it into a self-sustaining system. Give reason to justify your answer.
Solution
(a) (i) Kitchen Garden → A man made ecosystem / non-sustainable
Forest → Ecosystem maintained by nature / self-sustainable
(ii) In a jar containing water we can provide oxygen through a pump and add a few aquatic plants and animals to make it a self-sustaining system.
Justification –
• Oxygen is replenished continuously.
• Aquatic plants serve as food.
