After mangrove flowers are pollinated the plants produce seeds that immediately begin to germinate into seedlings. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.

Not many large animals can navigate the thick undergrowth and sinking mud pits of a mangrove forest, but for the Royal Bengal tiger, the treacherous habitat is the perfect hunting ground.
