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.3.3 Summarize the relationships between producers, consumers and decomposers including the positive and negative consequences of such interactions including Coexistence and cooperation Competition (predator/prey) Parasitism Mutualism 8.E.1.Understand the hydrosphere and the impact of humans on local systems and the effects of the hydrosphere on humans. 8.E.1.2 Summarize evidence that earth’s oceans are a reservoir of nutrients, minerals, dissolved gases and life forms: Estuaries Marine ecosystems Upwelling Behavior of gases in the marine environment Deep ocean technology and understandings gained.

Example: Example
Cooperation
Cooperation is an interaction in which organisms work in a way that benefits them all.
