Tidal:
The tide affects the rock pool habitat. When it is high tide the rock pool will get flooded, so all the organisms will get moved around. Some will even get pushed into different rock pools away from their home or pushed into the sea when the tide goes out. The tide could wash away the seaweed (the producer). The whole food chain would suffer because the producer has been removed.

The temperature affects the rock pool habitat. When its summer it will be hotter and the heat might evaporate some of the water, reducing the water level. This will affect the organisms because they will not have as much room to swim around in or they will get stuck out of the water and that means they will die. In winter the rock pool might freeze over. This means some predators won’t be able to get to their food. Another example could be the producer could die from lack of sunlight.
