Has nucleus encased membranes.

Mitochondria, chloloplasts, and golgi bodies.

Lacks nucleus and membrane bound cells.
Detritus Feeder:
Consumes decomposing organic material.
Processes organisms used to produce carbohydrates from carbon dioxide and water.
Movement of part of an organism towards light.
Movement of an organism toward water.
Growth response in relation to gravity.
A group of one species that inhabit a specific area.
Two or more species evolving together.
Gene pool:
Total number of genetic information within a population.
Convergent evolution:
Organisms evolve structures similar to other organisms in spite of their evolutionary ancestors being unrelated.
Divergent Evolution:
Process a species evolves into two or more different forms.
Ecological Community:
Two or more populations of different species occupying the same area.
Population Distribution Pattern Examples:
Clumped, random, or uniform
Survivorship Curve:
Plotting a life expectancy table on a logarithmic scale. There are three types.
Density Independent:
A factor that effects the population regardless of the population size.
Density Dependent:
A factor that effects the size of a population depending on the population size.
Organisms to produce offspring with little to no parental care and can only produce while they’re young.
Organisms live long lives and don’t produce until they are older, and produce slower.
Logistic Growth:
Population growth rate decreases with increasing numbers of individuals until it becomes zero when the population reaches a maximum.
Equation for Population Growth:
Population x Affluence x Technological Impact per Unit of Consumption


Fundamental Niche:
Full range of environmental conditions an organism can possibly occupy.
Realized Niche:
Space a viable population of species occupies in the presence of competitor species.
Specialist Species:
Organisms with relatively tightly defined niches and a narrow range of tolerance.
Generalist Species:
Able to thrive in a wide variety of environmental conditions.
The total mass of all the living material in a certain area.
Interspecific Competition:
Individuals from a different species competing for the same resource.
Intraspecific Competition:
Members of the same species competing for the same resource.
One member benefits from the relationship while the other is neither helped, nor harmed.
Structural Adaptations:
A physical trait that aids survival when a living thing evolves to its environment.
First Law of Thermodynamics:
Energy is neither created nor destroyed.
Second Law of Thermodynamics:
When energy is transformed from one form to another it becomes a lower quality of energy due to some being released as heat.
