Systems and Models
a system in which both materials and energy are exchanged across the boundaries of the system
Open System
species that are crucial to the maintenance of their ecosystem
Keystone Species
Type of curve that shows a boom and bust pattern
J Curve
energy can be transformed but not created or destroyed.
1st law of thermodynamics
simply move energy or matter from one place to another without changing it in anyway.
Transfer
is composed of a series of questions or statements based on the physical characteristics of the organisms concerned and operates as a kind of flow chart
Dichotomous Keys
one species depends on another for nutrition, harming the host organism in the process
Parasitism
Will increase or decrease the carrying capacity regardless of the size of the population
Density independent factors
This Pyramid has the strengths of being the most accurate and ecosystems can be compared.
Pyramid of Energy
involves transforming natural landscapes into built environments, resulting in loss of habitat
urbanization
dampens effects and promotes return to stability
refers to the maximum number of individuals that an environment can sustain with its available resources.
Carrying Capacity
Will increase or decrease the carrying capacity of a population based on the size of the population Examples include competition for resources and predation
Density Dependent Factors
illustrates the sequential transfer of energy and nutrients among organisms within an ecosystem, showcasing how energy moves from one organism to another according to their feeding interactions.
Food Chain
refers to the gradual build-up of non-biodegradable pollutants in an organism or trophic level over time. As a result, their concentration increases within the individual organism.
Bioaccumulation
when an ecosystem experiences a rapid, often irreversible change due to reaching critical thresholds.
Tipping Points
the entire range of conditions in which a species could live
Fundamental Niche
used for mobile species to estimate population size and density.
Capture-Mark-Recapture
Pyramid of Biomass
non-biodegradable pollutants accumulating in organisms over time – a process, leading to higher concentrations in the predator's body.
Biomagnification
Advantages of __________ _________ are unbiased and suitable for large populations
Random Sampling
Two different species of Warblers competing for the same seeds is an example of ___________
Interspecific Competition
describes the role an organism plays in its environment, including its interactions with other organisms, its habitat, and its diet.
Niche
denote an organism's role in the flow of energy within an ecosystem.
Trophic Levels
is the process by which organisms break down glucose to release the stored chemical energy for cellular activities.
Cellular Respiration
