Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans? (2 points) the levels of oxygen in the deep ocean are too high for many organisms to thrive. the low temperatures of the deep ocean would freeze most organisms. the salinity of the deep ocean is too high for most organisms to live. the lack of sunlight in the deep ocean limits the types of organisms that can survive.

The lack of sunlight in the deep ocean limits the types of organisms that can survive

Answer from: AADJ4

The lack of sunlight in the deep ocean limits the types of organisms that can survive.

Explanation:

Limiting factors are biotic or abiotic environmental factors that limit the distribution of organisms in that an environment. The factor varies from environment to environment, habitat to habitat and biome to biome.

Oxygen level, temperature, salinity and light are indeed some of the abiotic factors limiting the distribution of organisms in the seas/oceans.

However, oxygen levels in deep ocean cannot be too high for organisms to survive, and while variation in temperature do exist between shallow and deep ocean, it is never to the point of freezing. Also, while salinity do limit the distribution of organisms in the ocean, no part of the ocean is too salty for marine organism.

The major limiting factor is light. While the shallow end of the ocean is adequately illuminated to sustain photosynthetic and other diverse forms of organisms, the deep end is occupied by less diverse organisms that have developed necessary adaptation to low light.

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc). although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm. environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6). the geosphere consists of the core, mantle and crust of the earth.the atmosphere contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the hydrosphere contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found. ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields. the biosphere is the collection of all earth’s life forms, distributed in major life zones known as biomes: tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them. environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano) on may 18, 1980, mount saint helens, in the state of washington, erupted. this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere. such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic
