Answer: Some organisms navigate competition for space by specializing on different niches or depths in the intertidal. When scarce space does open up, organisms that are the fastest dispersers will colonize the space first and outcompete the other organisms. As the tides rise and fall, the salinity (salt concentration) constantly changes. Animals living in the intertidal zone must be able to tolerate wide salinity variations. If sufficient nutrients are available, intertidal animals reproduce rapidly, so they constantly compete for space, light, and food.
The best answer to the question that is being given above would be letter A. The most complex level of organization hierarchy that climate change could potentially affect is Earth's Biosphere - which holds every living thing in the planet. This climate change will destroy it more destruction to Mother Nature occurs.
