Unit 1
What is a hypothesis?
Educated guess
What is Temporal Isolation?
When 2 population reproduce at different time
What is Exponential growth?
Growth that occurs when a population grows
What is Primary succession ?
Occurs in an area that has been completely devoid of life,...Bare rock
What is coastal upwelling ?
Oceanographic phenomenon that occurs when wind blows parallel to the coastline, causing cold, nutrient-rich water from the oceans depths to rise to the surface
What is a Biotic Character?
A living factor
Ex. Animals, Fungi
What are Darwins 6 points ?
Overproduction, Competition, Genetic Variation, Adaption, Natural selection, Speciation
What 2 processes decrease the size of population?
Death and emigration
What is Secondary succession?
Occurs in an area that has been previously inhabited by living organisms but experienced a disturbance that disrupts the existing community....wildfire, hurricanes
What create the dead zone?
Excessive nutrients, like nitrogen and phosphorus, from sources such as agriculture and sewage, create the dead zone
What is an Abiotic Character ?
A non-living factor
Ex. Rock, Air
Whats a cladogram used for?
To understand the relationships between different species or groups of organisms
What is Logistic Growth?
Growth that takes into account limiting factors
Whats the difference between a food web and food chain?
Food chain shows the flow of energy and nutrients from one organism to another in an ecosystem
Food web is more complex, shows the flow of energy between multiple organisms
What is a watershed?
Area of land where all the water, such as rain or snowmelt, drains into a common waterway such as river, lake, or ocean
What's Quantitative and Qualitative ?
Quantitative is when your using numbers
Ex. ¨There are 5 apples and 6 bananas¨
Qualitative is when your describing something
Ex. ¨ The apples are red and the bananas are yellow¨
What is Geographic Isolation?
2 populations are separated by geographic barrier such a rivers, mountains or bodies of water
What 2 processes increase the size of population?
Birth and immigration
What is Mutualism ?
+,+
When both species benefit
Whats the dead zone in the ocean?
The area in the ocean with very low oxygen
What is the difference between Observations and Inferences?
Observation- Describing something or an event using your 5 senses
Inference- ¨educated guess¨ about something or event
List 6 hierarchical levels of classification
Domain
Kingdom
Phylum
Class
Order
Family
What shapes are Exponential and logistic growth?
J and S
How is parasitism different from predation?
In Parasitism, the parasite benefits while the host is harmed
In predation, the predator directly kills and consumes the prey for food.
What is biomagnification?
When toxins become more concentrated in the bodies of living things as you move up the food chain
