  2. Ecophysiology - Wikipedia

    en.wikipedia.org/wiki/Ecophysiology

    Heat transfer to the epidermis; The rate of evaporation; The rate of heat production; The hypothalamus plays an important role in thermoregulation. It connects to thermal receptors in the dermis, and detects changes in surrounding blood to make decisions of whether to stimulate internal heat production or to stimulate evaporation.

  3. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    Most energy is stored in organic matter of plants, and as the consumers eat these plants they take up this energy. This energy in the herbivores and omnivores is then consumed by carnivores. There is also a large amount of energy that is in primary production and ends up being waste or litter, referred to as detritus.

  4. Sound energy - Wikipedia

    en.wikipedia.org/wiki/Sound_energy

    In physics, sound energy is a form of energy that can be heard by living things. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.

  5. Ecological efficiency - Wikipedia

    en.wikipedia.org/wiki/Ecological_efficiency

    The rest of the energy input into cultivating feed is respired or egested by the livestock and unable to be used by humans. Out of a total of 28,400 terawatt-hours (96.8 × 10 ^ 15 BTU ) of energy used in the US in 1999, 10.5% was used in food production, [ 3 ] with the percentage accounting for food from both producer and primary consumer ...

    en.wikipedia.org/wiki/If_a_tree_falls_in_a_forest...

    The tree will make a sound, even if nobody heard it, simply because it could have been heard. The answer to this question depends on the definition of sound. We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it. When a tree falls, the motion disturbs the air and sends off air waves.

  7. Plant perception (physiology) - Wikipedia

    en.wikipedia.org/wiki/Plant_perception_(physiology)

    Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...

  8. Heat transfer physics - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer_physics

    The macroscopic energy equation for infinitesimal volume used in heat transfer analysis is [6] = +, ˙, where q is heat flux vector, −ρc p (∂T/∂t) is temporal change of internal energy (ρ is density, c p is specific heat capacity at constant pressure, T is temperature and t is time), and ˙ is the energy conversion to and from thermal ...

  9. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.
