What is ecology and why is it important to us? How o
Key Ideas and Study Guide
Chapter 3
autotroph commensalism carnivore herbivore
decomposer ecosystem abiotic factor heterotroph
parasitism scavenger habitat omnivore
community biosphere ecology mutualism
population niche biotic factor symbiosis
consumer producer trophic level predator
prey
1. Given an example of a specific organism be able to explain what its niche is.
2. Given a pair of organisms be able to determine the type of symbiotic relationship exists.
3. Make sure you understand the different types of feeding interactions (carnivores, herbivores,
et,)--be able to give an example of each
4. Make sure you know the difference between a heterotroph and an autotroph--be able to give
an example of each
5. Be able to interpret a food web or food chain. From a food chain you should be able to
determine if an organism is an autotroph, heterotroph, herbivore, carnivore, or omnivore.
6. Make sure you know what a food web or chain is used for. You should be able to make a
simple food chain if given animals the there roles in an ecosystem. Make sure you know that
producers always form the base of all food chains.
Chapter 4
Be able to define the following terms
limiting factor tolerance succession primary succession
climax community secondary succession biome photic zone
aphotic zone estuary intertidal zone plankton
permafrost humus pioneer species salinity
1. Be able to name each of the 6 major biomes. You should be able to identify each type in
terms of climate, average temperatures, amount of precipitation, type of soil, and the plants &
animals that live in each.
2. Make sure you can distinguish between primary and secondary succession.
3. Given a marine biome be able to identify where you would find each of the major zones & the
important features of each.
