Will competition increase or decrease the carrying capacity of an ecosystem?
decrease
200
Name 2 benefits from all animal behaviors
Protection and saving energy

What does Ichigo mean in Japanese?
First child or Strawberry
300
Bacteria in your stomach and intestines is what type of symbiotic relationship?
Mutualism
300
Describe the difference between an R and K selected species.
R--a species that invests minimal parental care and maximizes numbers of offspring.
K--a species that invests much parental care and minimizes offspring.
300
When a population grows past the ecosystem's carrying capacity, what happens to the population?
The population begins to die and returns back to carrying capacity
300
Name one way to decrease carrying capacity. Be specific
Add more predators, reduce prey, more competition
300
What is the difference between symbiosis and parasitism?
Symbiotic relationships are when two species live together and both benefit.
Parasitism--only 1 species benefits at the detriment of the other.
400
Explain why competition occurs between organisms
Organisms will fight over limited resources.

What is a Keystone species?
A species that, if it went extinct, would cause the ecosystem to collapse.

Kaos: 3 years
Kira: 1 year

Provide an explanation for why the population of hares are always greater than the population of lynx.
Hares receive more energy because they are lower on the food web compared to lynx.
