The primary role of the respirometry methodology in ecological research is to measure the metabolic rates of organisms and how they respond to environmental changes. This technique assesses oxygen consumption and carbon dioxide production, providing insights into an organism's energy expenditure and overall health. Respirometry can be used to evaluate the effects of temperature, habitat conditions, and food availability on various species. Understanding metabolic processes allows researchers to make predictions about survival strategies, species distributions, and the potential impacts of climate change on ecosystems.
