Unit Eight: Ecology- module a Flashcards
What is required of highly complex organization
constant input of energy and exchange of macromolecules
What is the Endothermic strategy
use of thermal energy generated by metabolism
What is the Ectothermic strategy
moving into sun/shade or aggregating with others
What is the relationship between metabolic rate and unit body mass
Smaller unit body mass higher metabolic rate
Larger unit body mass lower metabolic rate
What results from a net gain in energy
Energy storage or growth of organism
What results from a net loss of energy
Loss of mass and death
How does energy and population size connect
Changes in energy result in changes in population size
How can size and number of trophies levels be effected
Change in energy resources or change in producer level
Where do photosynthetic organism source energy
Sunlight
Where do chemosynthetic organism source energy
Small inorganic molecules present in the enviroment
Where do heterotrophs source energy
Metabolized carbohydrates, lipids, and protein
How do invasive species effect ecosystems
Can exploit niches and disrupt energy flow
How does resource availability effect ecosystems
Can result in uncontrollable population growth or decline and environmental changes
How does human expansion effect natural ecosystems
Exposer to diseases destroyed native species, habit change ensues
What effects habitat change
Geological, and meteorological events
