6.4: Ecosystems 3 Dimensions & Progressions
Unit 5
STANDARD 6.4.1
6.4.1 Analyze data to provide evidence for the effects of resource availability on organisms and populations in an ecosystem . Ask questions to predict how changes in resource availability affects organisms in those ecosystems. Examples could include water, food, and living space in Utah environments. MS-LS2-1
CONCEPTS
SKILLS
● Effects of resource availability on organisms and populations in an ecosystem ● Change in resource availability affects organisms in ecosystems
● Analyze Data ● Ask questions ● Predict
LEARNING PROGRESSIONS
● Organisms that live in ecosystems need resources like food, water, light, etc. ● Changes to ecosystems occur when resource availability changes ● Changes to ecosystems can affect the population of organisms in ecosystems VOCABULARY
● Ecosystem ● Organisms ● Resource
● FoodWeb ● Population ● Survival
POSSIBLE PHENOMENA
● Hunting permits are provided to maintain carrying capacity in Utah environments. ● On the Kaibab Plateau in Arizona, the deer population increased by 96,000 over 20 years and then decreased by 90,000 in the following 15 years. ● During a Spring that has heavy rainfall, wildfower populations increase.
END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS
● I can predict how changes in resources affect organisms in ecosystems. ○ Language Supports: ■ Verbs (belong to, have, be)
■ If/then clauses (if the _____ is decreased in a population, then _____., if ____ was removed from an ecosystem then _____ may occur.) ■ Connectors to show relationship (as a result of, therefore) ■ Mathematical thinking (the data indicates, patterns in the data suggest that ____.)
