Any microorganism that causes a disease
What is a pathogen
This pathogen is composed of a nucleic acid (DNA and RNA) and a protein coat.
What is a virus
Includes all living things in an area interacting with each other and their non-living environment
What is ecosystem
Refers to all non-living things
What is abiotic
An unexpected increase in the number of disease cases in a specific geographical area.
What is epidemic
This pathogen is considered to be nonliving because it needs a host cell to reproduce
What is a virus
This treatment is used to fight bacterial diseases
What is antibiotic
Refers to all living things
What is biotic
An organism that a parasite lives in or on.
What is a host
A feeding level in an ecosystem
What is a trophic level
A pathogen that is single-celled and reproduces asexually via binary fission
What are bacteria
The system that the human body uses to prevent and fight infections
What is the immune system
An organism’s role/job in its environment
What is niche
A symbiotic relationship between two organisms in which both organisms both benefit.
What is mutualism
An organism that transmits a disease without getting sick itself
What is vector
A weakened or dead form of a pathogen
What is vaccine
These are the proteins used to recognize infectious disease agents
What are antibodies
The maximum number of individuals of a species that an environment can support sustainably over time.
What is carrying capacity
The steady state of an ecosystem where all organisms are in balance with their environment and with each other
What is equilibrium
When a disease’s growth is exponential.It means a virus covers a wide area, affecting several countries and populations.
What is pandemic
This pathogen usually reproduces sexually and asexually (produces spores)
What is fungi
This occurs when mutant bacteria survive an antibiotic treatment and give rise to a resistant population.
What is antibiotic resistance
Anything that constrains a population's size and slows or stops it from growing
What is the limiting factor
A linear sequence of organisms through which nutrients and energy pass as one organism eats another.
What is a food chain
When a disease outbreak is consistently present but limited to a particular region. This makes the disease spread and rates predictable.
What is endemic
