Ecological Succession
100
Who wrote the Theory of Evolution by Natural Selection?
Charles Darwin
100
True or false : populations evolve, not individuals.
True
100
What causes evolution?
Natural selection over generations
100
Bat wings, cat paws, and whale fins are an example of this
Homologous structure
100
What does SUCCESSION mean?
gradual change in a community over time
200
What is an adaptation?
Any inherited characteristic that increases an organisms chance of survival
200
This is what is passed doen from parent to offspring: it controls the traits
DNA or genes
200
What is ONE example of present day evolution?
antibiotic resistant bacteria, pesticide resistant insects, herbicide resistant weeds
200
How are fossils used as proof of evolution?
Show how species change over time (oldest buried deepest, most recent near the surface)
200
What is PRESENT and already established in the ecosystem for SECONDARY succession but ABSENT in the ecosystem for PRIMARY succession?
soil
300
What is the definition of evolution?
the GRADUAL change in a species over LOTS and LOTS of time

Explain which mouse is better adapted to this environment.
The grey mouse is better adapted to this environment. Its fur color blends in with the environment and therefore is not seen by predators.
300
True or false: the FOSSIL RECORD shows direct evidence of the evolution of species over millions of years
TRUE
300
What does COMMON ANCESTRY mean?
that species that are related today shared a common ancestor at some point in their evolution
300
Name a PIONEER SPECIES
lichen, algae, mosses
400
Name THREE requirements needed for evolution to occur:
variation, competition, overproduction of offspring, adaptation
400
What characteristic must a population of organisms have to have the BEST chances of surviving environmental change?
variation in genes
400
Fill in the blank: Organisms with traits that _____ their chances of surviving and reproducing in their environment tend to produce more offspring
Increase
400
All mammal embryo's look remarkably the same at the 6 week developmental stage. What is this evidence for?
Common ancestry
400
Name a disturbance that can result in a SECONDARY SUCCESSION
wildfire, volcanic eruption, farmland abandonment
500
Describe Lamark's theory of Use and Disuse
Traits that are ACQUIRED during an organisms lifetime can be passed to the next generation
500
What is an example of MOLECULAR EVIDENCE that can prove 2 species are closely related?
DNA analysis or amino acid sequencing
500
Explain SURVIVAL OF THE FITTEST
Those organisms best adapted to their environment survive and reproduce, passing their traits to the next generation
500
How can comparing biological molecules be used to see how related 2 species are?
Comparing DNA or amino acids of species shows us who is related. The more similar the DNA is, the more recently they shared a common ancestor

In 2024, the STUMP POND DAM on LI broke, freeing the Nissequogue river to flow freely. The land that was once flooded is now dry, and grasses and shrubs are growing. What type of succession is this?
Secondary succession
