limitations of resources
Answers
Answer:“Resource limitation” is generally associated with reductions in rates of resource uptake, biomass production, or population growth that are caused by low availability of energy and materials such as carbon, water, and other essential elements (nutrients). All organisms can be limited by any resource, and thus limitation is a universal phenomenon. Here, resource limitation is addressed primarily in terrestrial plants but also terrestrial herbivores and microbes. As noted in the Historical Accounts section, the concept of limitation goes back to the early 1800s, primarily from agronomic studies. The early understanding of limitation developed to incorporate a rich body of theory and empirical investigations of controls over limitation. A number of experiments and surveys coupled with models and physiological investigations of organisms helped to develop our understanding of limitation by individual resources (water, nutrients, light, and carbon dioxide), as well as multiple resources (co-limitation).
