Rising air always cools, and, conversely, sinking air always warms. This type of temperature change, which is caused simply by ascent or descent in the atmosphere, is called adiabatic cooling or warming.

The horizontal transport of any atmospheric property by the wind is called advection. A heat transfer process in the atmosphere that depends upon the movement of air is: Convection.

Perspiration cools the body by latent heat transfer. Sweat helps cool you down by releasing moisture onto your skin. But that's not all that's going on. On a hot day, your sweat evaporates from your skin taking a little bit of your body heat with it.

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Organisms which depend on Producers for nutrition are called heterotrophs or consumers.

Phytoplankton are producers of lakes.
