- Topic:04- Ecology
- Subject(s):Science
- Days:24
- Grade(s):9
Key Learning:
Living and non-living things within an ecosystem affect each other. Species survive because of and in spite of interactions with other species.
Unit Essential Question(s):
Concept: Biotic and Abiotic Factors
Distinguish between biotic and abiotic factors.
Use a diagram to show the flow of matter through each of the major biogeochemical cycles.
Describe how biogeochemical systems limit the ecosystem components.
Concept: Biomes
Discuss the biotic and abiotic factors that impact an aquatic system.
Describe the major climatic trends in ecosystems. Explain how biomes are shaped by major climatic trends.
HOTS: Comparing/contrasting or Deductive reasoning could be used to demonstrate the ET LEQ.
Concept: Food Chains and Food Webs
Describe the role of producers, consumers, and decomposers in an ecosystem. Describe the flow of matter and energy through food chains and webs.
Identify trophic levels. Describe how as energy moves from one trophic level to the next that only 10% can actually be used at the next level. Explain how the law of conservation of matter applies to trophic levels.
HOTS: Inductive reasoning, Classifying/Categorizing, Comparing/Contrasting or Deductive Reasoning could be used to demonstrate the ET LEQ.
Lesson Essential Question(s):What influence do abiotic and biotic factors have on an ecosystem?
(A)What similarities exist in the cycling of matter in each of the major biogeochemical cycles?
(A)How do biogeochemical systems impact ecosystem components?
(A)Concept: Competition and Limiting Factors
Compare and contrast density-dependent and density-independent limiting factors.
Describe how limiting factors affect the growth, biotic potential, and carrying capacity of populations and communties.
HOTS: Constructing Support or Deductive reasoning could be used to demonstrate the ET LEQ.
Concept: Succession
Compare and contrast primary and secondary succession. Give examples of primary and secondary succession.
HOTS: Deductive Reasoning can be used to demonstrate the ET LEQ.
Concept: Human Impact
Describe the various types of renewable and non renewable resources that human use to produce energy. Discuss the positive and negative consequences of each type of resource. Discuss the impact that human activities have on environmental systems including our consumption of natural materials and disposal of waste products.
Examine the impact that human activities have on the biodiversity of the Earth. Discuss how other naturally occuring catastrophic events can cause biodiversity to decrease.
HOTS: Inductive Reasoning, Deductive Reasoning, Analyzing Perspectives or Constructing Support could be used to demonstrate the ET LEQ.
Lesson Essential Question(s):How do scientists determine the carrying capacity for an ecosystem?
(A)How does competition and environmental changes impact the survival of a species?
(A)How does a food web illustrate competition for energy resources?
