Linear representations of how species in a community consume each other
What is the food chain?
The rate at which energy is captured and assimilated by the producers.
What is the gross primary productivity?
A range of conditions such as temperature, salinity, pH, or sunlight that an organism can endure before injury or death
What is ecological tolerance?
The way that populations and species of a organisms change over time
What is evolution?
Species found in only one area that are extremely vulnerable to extinction.
What are endemic species?
Complex representation of multiple species energy transfer.
What is the food web?
The amount of energy received by primary producers if the sun puts out 300,000 joules of energy.
What is 30,000 Joules?
The area labeled A represents this zone.
What is zone of optimum?
Certain genetic traits are more likely to survive and reproduce in certain conditions
What is natural selection?
Species that have a large effect on the types and abundance of other species in an ecosystem
What are keystone species?
The percent of energy received from one trophic level to the next.
What is 10%?
The organism classification that eats primary producers.
What are herbivores?
Range where organisms survive but experience some stress such as infertility, lack of growth, decreased activity
What is zone of physiological stress?
A trait that improves the ability of an individual organism to survive and reproduce
What is adaptation or adaptative trait?
What is secondary succession?
The relationship between consumers and producers at different trophic levels in an ecosystem.
What is a food pyramid?
Absorb any dead material and break it down into simple nutrients or fertilizers
What are decomposers?
The environmental factor that is in short supply or causes the stress on the system
What are limiting factors?
When an ancestral species splits into two or more descendant species
What is speciation?
Natural disruptions can be ___________, ___________ or _____________.
What are periodic, episodic or random?
The order of the trophic levels from the bottom of the pyramid to the top.
What is primary producer, primary consumer, secondary consumer, tertiary consumer?
When energy is lost between trophic levels it is released as ______________ and _____________.
What is waste and heat from respiration?
The x and y axis
What is Environmental Gradient X and Abundance Y?
The two causes of speciation.
What are geographic isolation and reproductive isolation?
overpopulation of species which can lead to extinction can come from the loss of this type of interaction.
What is predator/prey?
