What are the three types of organisms in an ecosystem?
Producers, Consumers, and Decomposers
100
Name the 2 simple (quick) ecological relationships
Predation and Competition

Nitrogen and carbon
200
What is the location where a community or population lives called?
A habitat

Name ONE of the 3 symbiotic relationships
Parasitism, Mutualism, Commensalism

When analyzing a food web, the arrowheads point to what?
The organism doing the eating / getting the energy
300
What's the difference between abiotic and biotic factors?
Abiotic: Non-living parts of an ecosystem
Biotic: Living parts of an ecosystem
300
What do autotrophs do?
Make their own food to obtain energy/food source for other organisms
300
What is Commensalism? OR name an example
One organism gets food from the other organism without harming them or the other benefiting / Barnacles on whale

How do heterotrophs obtain energy?
By consuming other organisms

Describe what the study of Ecology is in your own words
Branch of biology that deals with the relations of living organisms and their surroundings

Describe the 10% Rule
When energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on
