Study Guide Lesson 2
1.
Define Levels of Ecosystem organization: species, habitats, populations, community, ecosystems and ecology.
Species: a group of organisms that can interbreed and produce fertile offspring.
Habitat: the environment in which a species normally lives or the location of a living organism.
Population: a group of organisms of the same species who live in the same area at the same time.
Community: a group of populations living and interacting with each other in an area.
Ecosystem: a community and its abiotic environment.
Ecology: the study of relationships between living organisms and between organisms and their environment.

Organization of the environment: Living systems move toward order or death. The movement toward order or equilibrium
is ecological succession. Ex. Forest Fire
Critical factor
Adaptations
Carrying capacity
Habitat and niche
Relationships between organisms: Competition, predation, symbiosis
Symbiosis: Parasitism, mutualism, commensalism
Limiting factor and carrying capacity
Discuss the concept that ecosystems are essentially energy systems.
What is an ecosystem? How does it differ from a community?
Vocabulary: mutualism; predation, competition, symbiosis, commensalism, compare, contrast, relationship.
Be able to read, analyze, and give complete answers to questions like these:
14. If given an example of a relationship between two organisms be able to identify it as predator-prey (predation),
completion, mutualism, parasitism, commensalism, symbiotic.
15. Be able to read a carrying capacity graph: look at the following examples
