Answer and Explanation:
We know that shrubs are primary producers and mountain lions are secondary or tertiary consumers. Therefore, mountain lion cannot directly feed on shrub rather need a herbivore. Therefore, to develop a food chain including mountain lion and shrub, we need to have at least one herbivore. If we add a deer between these two, the food chain willl be complete. The deer (herbivore) will eat shrub and mountain lion (carnivore) will eat deer. The food chain can be written as follows
<em>Shrub -> deer -> Mountain Lion</em>
They only tested two to have a solid hypothesis you need a larger group.

Agroforestry is a kind of practice in which trees are grown along with the crop which benefits the crop; there is different alley cropping, silvopasture and forest cropping.
Combining forests and agriculture seem to perform many benefits to the farmer. This type of practice has enabled farmers to show nutrient cycling, crop productivity and change in the micro climate of the place.
