When incoming energy from the sun is absorbed, Earth warms. When energy is released from Earth into space, the planet cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including changes in greenhouse gasses; variations in the sun’s energy reaching Earth; and changes in the reflectivity of Earth’s atmosphere and surface.

Thus, the constraints are the shape of the curve of diminishing returns and the travel time (the time it takes to make a round trip from the nest to a patch and back).

Autotrophs, like plants, create organic molecules via photosynthesis, whereas heterotrophs, such as humans, obtain energy by consuming organic matter.

Energy is exchanged between them and their surroundings as they use energy from the sun to perform photosynthesis or consume energy-storing molecules and release energy to the environment by doing work and releasing heat. To appreciate the way energy flows into and out of biological systems, it is important to understand two of the physical laws that govern energy.

The chemical and physical properties of microbial pathogens—both cellular and acellular—dictate their habitat, control their metabolic processes, and determine how they interact with the human body. This appendix provides a review of some of the fundamental principles of chemistry and physics that are essential to an understanding of microbiology.

If the flux of material into and out of a given reservoir is the same for some period of time, that reservoir is said to be in a steady state.

Handling time (h) is the amount of time it takes the predator to handle the food, beginning from the time the predator finds the prey item to the time the prey item is eaten.

Pyruvic acid then undergoes fermentation in yeasts (producing ethanol and CO2) or lactic acid in red blood cells and muscles. Both fermentation routes are energy-inefficient. In contrast, pyruvic acid is fully oxidized in mitochondria during cellular respiration, capturing approximately 40% of glucose's energy as ATP.

This organization requires a continuous input of energy, primarily managed through cellular metabolism. ATP serves as the key energy currency, facilitating biochemical reactions governed by Gibbs free energy (∆G). Key principles include standard free energy change, Le Chatelier’s principle, and energy storage in triphosphates.
