Populations and Ecosystems
8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment.
8.L.3.1 Explain how factors such as food, water, shelter, and space affect populations in an ecosystem.
8.L.3.2 Summarize the relationships among producers, consumers, and decomposers including the positive and negative consequences of such interactions including: coexistence and cooperation, competition (predator/prey), parasitism, mutualism.
8.L.3.3 Explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide and oxygen).
