PLANT GROWTH

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What could happen to plants that have to compete for resources?
A
They could be strong and grow more due to getting stronger from adapting to competing with other plants/getting less nutrients
B
They could be weak and grow less due to getting weaker from competing with other plants/getting less nutrients
C
They would be fine, they just need to have a good cry and move on
D
None of the above
Explanation: 

Detailed explanation-1: -Competition is generally understood to refer to the negative effects on plant growth or fitness caused by the presence of neighbors, usually by reducing the availability of resources. Competition can be an important factor controlling plant communities, along with resources, disturbance, herbivory, and mutualisms.

Detailed explanation-2: -Plants compete for nutrients by pre-empting nutrient supplies from coming into contact with neighbours, which requires maximizing root length.

Detailed explanation-3: -The way organisms compete with each other determines species distributions, population dynamics, community structure, food webs, and social dominance hierarchies. Competitive interactions over time manifest themselves in physical and behavioral adaptations that shape the evolution of a species.

Detailed explanation-4: -The competitive exclusion principle says that two species can’t coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.
