The decisions we make while we browse the internet are suprisingly similar to the ones animals make as they forage for food...here's why.

Optimality models: tools used to evaluate the costs and benefits of different organismal features, traits, and characteristics, including behavior, in the natural world.
Optimal foraging theory: a behavioral ecology model that helps predict how an animal behaves when searching for food.
Marginal value theorem: an optimality model that describes the strategy that maximizes gain per unit time in systems where resources, and thus rate of returns, decrease with time.
Central place foraging: a model for analyzing how an organism traveling from a home base to a distant foraging location can maximize foraging rates.

Observing the effects of microbes using satellites can give us all sorts of useful information about life on Earth ... and other planets too.

Microbe - an organism (such as a bacterium or protozoan) of microscopic or ultramicroscopic size.

Remote sensing - the scanning of the earth , especially by satellite or high-flying aircraft, in order to obtain information about it.

Pathogen - a bacterium, virus, or other microbe that can cause disease.

Chlorophyll - a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.

Phytoplankton - photosynthesizing microscopic biotic organisms that inhabit the upper sunlit layer of almost all oceans and bodies of fresh water on Earth.

Cholera - an infectious and often fatal bacterial disease of the small intestine, typically contracted from infected water supplies and causing severe vomiting and diarrhea.

Evaporite - a natural salt or mineral deposit left after the evaporation of a body of water.

Microbially induced sedimentary structures (MISS) - primary sedimentary structures formed by the interaction of microbes with sediment and physical agents of erosion, deposition, and transportation. ___________________________________________
