Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Quinine is obtained from the bark of Cinchona officinalis (family Rubiaceae). The bark of this plant contains about 30 alkaloids including quinine, cinchonine quinidine and cinchonidine. Belladona (Atropa belladona family Solanaceae) yields three drugs- atropine, scopolamine and belladona. Ramvolffia serpentina (family - Apocynaceae) is a perennial under shrub. Its dried roots contain reserpine and other alkaloids like serpentine, serpentinine etc. Aconite is obtained from the tuberous roots of Aconitum napellus (family-Ranunculaceae).

Concepts Used:
Population Interactions
Population interaction is generally between two different species populations.“Population interaction is the interaction between different populations. It refers to the effects that the organisms in a community have on one another.”
An ecosystem is a geographic area wherein plants, animals, and many other organisms, alongwith weather and landscape, work together to form a bubble of life.
Types of Population Interactions:
Interactions can be beneficial or neutral or detrimental. Accordingly, there are six types of population interaction.
The different ways populations interact with each other can be summarized under the following headings.
- Competition
- Predation
- Herbivory
- Mutualism
- Commensalism
- Parasitism
