Organisms that are similar to each other & are capable of breeding and producing fertile offspring
What are species
The cause of the buffalo population increase from 1960-1975
What is elimination of disease (Rinderpest)
Change in species over time
What is evolution
This is how long it takes bacteria to reproduce
What is 20 minutes
Plant eaters
What are herbivores
Non-living parts of the environment (EX. precipitation, temperature)
What is an abiotic factor
The two causes of the buffalo population decrease after 1975
What are drought and poachers
This type of reproduction results in the most diversity
What is sexual reproduction
Bacteria reproduce using this type of asexual reproduction
What is binary fission
Changes in DNA are called this
What are mutations
Living parts of the environment (EX. plants, animals)
What is a biotic factor
The maximum amount an environment can support based on its available resources
What is carrying capacity
The number of chromosomes passed to an offspring by each parent (specific number)
What is 23
Since antibiotics were not able to kill Addie's infection, we can label her bacteria as this
What is antibiotic resistant (specifically pan-resistant)
More wildebeests=less grass=?
What is less fuel for fires
Includes all organisms of the same species in a particular area
What is population
The wildebeests hold this role in the Serengeti. Without them, the ecosystem would be much different.
What is a keystone species
In a biomass pyramid, this is the percentage of energy that is passed up the pyramid to the next organism
What is 10%
If an antibiotic is 80% effective, what percentage of bacteria will be alive after the dose?
What is 20%
Another name for a family tree used in science
What is a pedigree
Includes all biotic and abiotic factors in the environment
What is an ecosystem
When a large portion of the cattle/buffalo were vaccinated, the wildebeests also improved even though they were not vaccinated. What phenomena is this due to? (Think elimination of polio)
What is herd immunity
Charles Darwin developed this theory for how evolution occurs. Only the most fit individuals (most adapted to their environment) will survive and pass on their genes to their offspring. Eventually, those genes will become most common
What is natural selection
Bacteria experience this type of growth
What is exponential growth
When resources are limited (EX. space in the Serengeti), it leads to this interaction between organisms
What is competition
