Energy budget
Energy Budget
The Energy Budget (pronunciation: /ˈɛnərdʒi ˈbʌdʒɪt/) is a concept in Biological Sciences and Earth Sciences that describes the total amount of energy entering, exiting, and being stored in a system. It is a fundamental principle in the study of Ecology, Climatology, and Physiology.
Etymology
The term "Energy Budget" is derived from the words "energy", which comes from the Ancient Greek word "energeia" meaning activity or operation, and "budget", which originates from the Old French "bougette" meaning a small bag.
Definition
In the context of Ecology, an Energy Budget refers to the balance of energy intake, expenditure, and storage in an organism. It is a critical factor in understanding the survival, growth, and reproduction of organisms.
In Climatology, the Energy Budget is used to describe the balance of incoming and outgoing radiation in the Earth's atmosphere and surface. It is a key concept in understanding global warming and climate change.
In Physiology, the Energy Budget refers to the balance of energy intake (food), energy expenditure (metabolism and physical activity), and energy storage (as fat or glycogen) in the human body. It is a fundamental concept in nutrition and weight management.
Related Terms
- Energy Balance: A state in which energy intake equals energy expenditure, leading to no net change in body size or body composition.
- Energy Expenditure: The total amount of energy used by the body for growth, maintenance, and physical activity.
- Energy Intake: The amount of energy derived from food and drink consumed.
- Energy Storage: The retention of excess energy for future use. In organisms, energy is primarily stored as fat or glycogen.
