The size of plasmids ranges between 1 and 200 kbp (kilo-base pairs) and a DNA fragment that can be inserted into a plasmid vector is up to 20 kbp. Artificially constructed plasmids are often used as vectors in genetic engineering to clone and amplify (or express) particular genes.
In an ecosystem, all the trophic level in a food web are closely interlinked and any change in one level is bound to affect the other levels. The various trophic levels may correspond to producers (such as grass and plants), primary consumers (such as deer), secondary consumers (such as tigers or lions, etc.), etc. If we reduce the land available or necessary for sustaining the ecosystem by half (5 acres instead of 10 acres).
