Environmental Science (L1) Unit 2 Objectives: Populations and Intro to Ecology
Note: These objectives are a list of the main ideas that will be discussed in this unit. Please make sure that you also review all book sections, labs, activities, and notes sheets from class.
Make sure to thoroughly define each term and explain each concept.
You should be able to:
1.
Define all the possible niches that an organism can fill in a food web and cite examples for each niche. (Notes and 1.2 in text).
2.
Create a food web, or analyze one given, using all the possible niches involved and recognize a feeding niche from a chain.
3.
Describe the impact a keystone species can have on a foodweb. (Notes)
4.
Be able to explain all the possible paths (flow) of energy and matter in an ecosystem.
Diagram and explain the concept of a biomass and number pyramid. (Notes and 1.6 in text)
5.
Be able to diagram and define the processes involved in the carbon/oxygen cycle. (Notes, lab activity, and 1.7 in text)
6.
Be able to diagram and define the processes involved in the hydrologic (water) cycle. (Notes and 1.7 in text)
7.
Be able to identify all the processes and components of the nitrogen cycle. Recognize which organisms are responsible for the processes and the end product of each process. (Notes, diagram, and 1.7 in text)
8.
Be able to explain the concept of ecological succession with examples. Describe the biotic and abiotic characteristics of each stage in the succession of a pond and a forest. Give examples of disturbances that can change the rate of succession (Notes and 1.8 in text)
9.
Be able to answer all the assigned questions regarding the text and the case studies.
