Document Summary
A group of individuals of the same species. Species that interact with each other within an area. Consists of all biotic and abiotic components in a region. Factors that explain the abiotic conditions: proximity to ocean, mountains. Water takes a lot of energy to heat up or cool down so having a large body of water helps balance temperature. Force air to move up -> vapor cools down -> rain. Moderate temperature = optimal temperature = more species. Optimal conditions promote growth because energy is used for growth instead of maintenance/sustainability. Nitrogen and phosphorus are most abundant in deep water because of debris and dead organisms settled at the bottom. Barnacles are found in the upper boundary whereas mussels are found in the lower boundary of the intertidal zone. Upper boundary is more stressful because of its abiotic factors such as the change in temperature and moisture level during high and low tides.
