Biotic and Abiotic Factors in Ecosystems
Essential Standard 6.L.2 - Understand the flow of energy through ecosystems and the
responses of populations to the biotic and abiotic factors in their environment.
Clarifying Objective 6.L.2.1 - Summarize how energy derived from the sun is used by
plants to produce sugars (photosynthesis) and is transferred within food chains and
food webs (terrestrial and aquatic) from producers to consumers to decomposers.
Learning Objective: Students will categorize the living and nonliving
factors in an ecosystem.
