After mangrove flowers are pollinated the plants produce seeds that immediately begin to germinate into seedlings. LS2.B Cycles of Matter and Energy Transfer in Ecosystems: Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem.
