Genetics
The molecule that chromosomes are made of; it carries genetic information.
What is DNA?
An organism that eats other organisms in order to obtain energy
What is a Consumer?
The process by which genetic information is passed from parents to offspring.
What is Inheritance?
When one organism eats another one.
What is Predation?
When organisms better adapted to their environment are able to survive and reproduce.
What is Natural selection?
A section of a chromosome that codes for a specific protein.
What are Genes?
The process plants use to change CO2 into carbohydrates like glucose.
What is photosynthesis?
An organism or population’s ability to survive and reproduce.
What is Fitness?
The variety of different species within an ecosystem.
What is Biodiversity?
The process of making an area more "city-like," altering natural habitats.
What is Urbanization?
Folded molecules that are made of amino acids.
What are Proteins?
An organism that uses the sun’s energy to create carbohydrates.
What is a Producer?
An inherited trait that increases an organism's fitness in its specific environment.
What is an Adaptation?
The maximum number of individuals of a species that an ecosystem can sustainably support.
What is carrying capacity?
The process where large habitats are divided into smaller, isolated patches by roads or buildings.
What is Fragmentation?
The building block molecule that proteins are made of.
What are Amino acids?
The process all organisms use to break down carbohydrates like glucose.
What is Cellular Respiration?
A random change in a gene that creates a new version (allele).
What is a Mutation?
The ability of an ecosystem to withstand change.
What is resilience?
A resource or condition that limits the growth or distribution of a population.
What is a Limiting Factor?
Different versions of a gene.
What are Alleles?
The position in the food web an organism occupies, such as 1st or 2nd consumer.
What is a Trophic level?
The differences in DNA among individuals; the "raw material" for natural selection.
What is Genetic Variation?
A species that has a large or balancing effect on an ecosystem even if their population is small.
What is a keystone species?
Something that affects an organism's ability to survive and reproduce.
What is Selection Pressure?
