reproductive process where offspring develop from a single parent, resulting in genetically identical clones.
Asexual reproduction

Which of these is the prey?
Blue/Top Line
100
When wind or water gradually wear away soil, rock, or land
Erosion

Evolution is a change in allele frequency over time in a ________?
Population
200
Overtime which trait will be favored by natural selection and what is the selecting agent?
Tall/Long Necks; Starvation/Food
200
Why has this population stopped increasing?
Due to limiting factors such as food and disease
200
During which period of time did this population have an excess of resources?
Day 10-18
200
Burning fossil fuels releases what gas that contributes to the climate crisis?
CO2 (Carbon Dioxide)
300
Scientist studied the beak length of finches on an island before and after a draught and found the following results. Which birds had low fitness? 
Small beaks
300
Scientist are trying to determine the evolutionary lineage between birds and dinosaurs by study the archaeopteryx. Which evidence of evolution would best help them track these changes from millions of years ago?
Fossils (in the ground)
300
A Climax community will?
A) Be able to waistband disturbances
B) Have the most biodiversity
C) Slowly disappear over time
D) Remain stable until a change occurs
D

What is happening to Biodiversity between 1990-2014?
Decreasing
300
What are the three R's? Put a star next to the one with the biggest positive impact on the environment.
*Reduce
Reuse
Recycle
400
What is causing evolution to happen? (The driving force of evolution)
Natural Selection
400
Why is genetic diversity (biodiversity) important in an ecosystem?
Makes it more stable/ more resistant to changes
400
Which organisms is an omnivore?
Herring
400
Which population had an evolutionary advantage?
Butterflies with Eye Spots
400
What can be done to reduce soil erosion? (Need 2 answers)
No Till Farming, Plant Cover Crops, Plant Trees.

Scientist are studying the embryos of many animals and compared them below. What conclusion may they come to about how these organisms evolved?
They may share a common ancestor/evolved from similar place
500
During succession, biotic factors will change over time. What is changing within the ecosystem to facilitate the change in biotic factors?
Abiotic factors (soil,nutrienst, water availability)
500
Explain why this trend may be happening as it relates to natural selection.
Predators are scared of butterflies with eye spots so they do not eat them as frequently as those without.

What are way to reduce Eutrophication/pollution of the big Sioux River
Eutrophication: Less fertilizer, Less Run off (farming practices), Less animal waste -> River
Pollution: Less pesticides, don't let chemical go down storm drains, Clean up animal waste,
