Mutualism Mutualism is a biological interaction between two organisms. Most mutualisms are facultative‚ meaning the partners can successfully live apart. However‚ some mutualisms are so intimate that the interacting species can no longer live without each other; they have a mutually obligate interdependence. Examples: As the bee or butterfly sips

ELSEVIER Why Do People Love Their Pets? John Archer Department of Psychology‚ University of Central Lancashire‚ Preston‚ United Kingdom The evidence that people form strong attachments with their pets is briefly reviewed before identifying the characteristics of such relationships‚ which include pets being a source of security as well as the objects of caregiving. In evolutionary terms‚ pet ownership poses a problem‚ since attachment and devoting resources to another species are‚ in theory‚ fitness-reducing

Weather and Atmospheric Water Humidity- the amount of water in the air in a particular spot. Relative Humidity- the percentage of water vapor a certain volume of air is holding relative to the max amt it can contain. 80% humidity means that it is holding 80% of the total amt of water that it can hold at that temp. Heat Index- shows what the temperature feels like due to humidity. Dew Point- the point at which air becomes saturated with water. Water will condense from the air as dew‚ if the

Biotic factors are created by living organisms within the environment which are affected from the interaction of organisms. Such factors are predation‚ mutualism and commensalism (Biology Online‚ 2014).
