Grouping Behaviors
What are some pros and cons of grouping in a pack
Ex: Wolves, Fish
Pros: Stronger hunting, Easier to reproduce, More protected from predators
Cons: More competition for food, more easily transmitted diseases, and more obvious to predators around
What is on the top of the trophic pyramid.
Apex predator
What is the name when people cut down trees and are destroying habitats.
Deforestation
What is an environmental issue
A problem that threatens the Earth's natural ecosystems is often caused by human activity.
Ex: Global Warming, Deforestation, Over-Harvesting
What is a limiting factor
Something that keeps the population down so it doesn't exceed the carrying capacity.
What are the 4 levels on a trophic pyramid called
Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers, Quaternary Consumers/Apex Predators
Optional: Decomposers
What is the human impact on global warming
Humans burn fossil fuels for things like cars and factories, causing carbon dioxide and methane (greenhouse gases)

Yay, you found a freebie
What is the 10% rule?
Only 10% of the energy travels up the trophic pyramid. (plants=100% primary consumer=10% secondary consmuer=1% tertiary consumer=.1% Quantranary consumer/Apex=.01%)
FREEBIE
Congrats! You got a freebie
How might a disruption, such as an invasive species, change the carrying capacity for an organism that is in direct competition with that invasive species?
The population will go down because the carrying capacity cannot hold that many things in the ecosystem.
