Question

Two species of plants that are competitors in nature are grown together in the greenhouse. When they are fed additional nitrogen, species A thrives at the expense of species B. When they are fed additional phosphorus, species B thrives at the expense of species A. Both species show improved growth when they are both given additional sunlight, but additional moisture has little effect on either one. Based on this information, which of the following is most likely to be the limiting resource for both species?1. Commensalism2. Predation3. Herbivory4. Competition5. Amensalism

Answer 1

Answer:

4. Competition

Explanation:

• As the to species of the plants are full competitors pf the space and they being grown together in the same greenhouse the species A thrives at the expanse of the specie B this is a due to the fact that species that compete among each other for the survival of the sunlight.  

• And moisture the species that dominates over the other species will continue to grow at the expense of the other specie and thus competition will most likely be limiting factor in resource consumption.
