Answer:Limiting factor is a factor which can limit the abundance, distribution of the species in an ecosystem this can be a resource, predator or natural disaster. The black swallowtail butterfly feeds on endangered plant named Candy's dropwort. If the plants continue to decrease the population of black swallowtail butterly will also decrease as decrease in the plant population will act as a limiting factor for the growth of butterfly population.

Answer:
Atmospheric carbon dioxide is the raw material for photosynthesis, which plants  rely on for producing sugars and other organic compounds.
Explanation:
The most accurate statement that supports the researcher's claim is that atmospheric carbon dioxide is the raw material for photosynthesis. 
Photosynthesis is the process by which green plants manufactures their food in the presence of carbon dioxide and water using sunlight. 
The product is usually glucose and oxygen. 
        The chemical equation is shown below; 
            6CO₂  +  6H₂O → C₆H₁₂O₆ + 6O₂
This raw material is a by-product of cellular respiration in human beings. Other process also releases carbon dioxide. Green plants uses this organic material to manufacture its food through photosynthesis. 
We can attribute the increased growth rate in plants to the proliferation of the gases in the atmosphere.
