unit 1 and 2

• Tropical rainforests have lots of rainfall and are very warm
• Temperate deciduous forests have moderate precipitation and moderate temperatures.
• Anthropogenic are things originating from human activity
• The 4 ecosystem services are regulating, supporting, cultural, and provisioning
• gross primary productivity - cellular respiration = net primary productivity
• The first trophic level is primary producers
• the second trophic level is primary consumers
• the third trophic level is secondary consumers
• the fourth trophic level is tertiary consumers
• genetic diversity is the biological variation that occurs within species
• species diversity is the number of different species in a particular area and their relative abundance
• habitat diversity explores the variations in ecosystems within a specific geographic area
• Parasitism is when a parasite feeds on a host
• Mutualism is when both organisms live together and benefit each other
• Commensalism is when there are 2 species but only 1 species benefits and the other has little or no effect
• Photosynthesis reduces the amount of carbon in the atmosphere
• Intertidal zones are areas that form the narrow band along the coast that experience a range of environmental conditions
• Primary successions is when a patch of land that has never been exposed to life is exposed to life
• the edge effect is when a secondary biome is created from broken off ecosystems
• Convergent evolution is the process where organisms not closely related independently acquire similar characteristics while evolving in separate and sometimes varying environments
• Adaptive radiation is the development of many species that are derived from a single, ancestral population
• Interspecific competition is competition among members of different species
• 10% of energy is lost through transfer
