Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!

<span>The choices for this question are:
</span>-is biologically magnified in ... are recycled in
-is dissipated in ... flow through
-flows through ... are recycled in
-is continuously supplied to ... are continuously removed from
<span>-is recycled in ... flow through</span><span>

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option. 

Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.  
</span><span>
Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled. 

In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>

What is shown in the image below? A food web titled Chesapeake Bay Waterbird Food Web. It shows a very complex food web with man
ELEN [110]

Answer A)

As the diagram shows, there are five trophic levels which can be seen in this food web. The first trophic level is the organisms which are able to produce their own food by the process of photosynthesis. These include organisms like phytoplankton, S A V, vegetation. The second trophic level is that of the herbivores which includes  zooplankton, benthic invertebrates, herbivorous ducks, geese and mute swans. The third trophic level is the primary consumes which includes small planktivorous fish, bivalves. The fourth trophic level is the secondary consumers which includes gulls and terns, wading birds, large piscivorous fish, sea ducks, tundra swan. The fifth torphic level is that of the tertiary consumers which includes osprey, bald eagle.

Answer B)

Produces are organism which can make their own food.<em> An example of producers in this question is phytoplankton.</em>

Herbivores are organism which only feed on the primary producers.<em> An example of herbivores in the given question is  herbivorous ducks.</em>

Carnivores can be described as organisms which feed on other animals. <em>An example of carnivores in the given question is bald eagle.</em>

Answer C)

As energy moves up the trophic levels in a food chain or food web, it reduces abundantly. This is because most of the energy is lost at each trophic level in the form of heat. Only 10% of energy is recorded to be transferred from one trophic level to another. The rest is lost mainly in the form of heat to the environment.

Answer No D)

1) Carbon moves from the plants to the animals which eat them.

2) The carbon dioxide released into the atmosphere by animals is taken by the plants for the process of photosynthesis.

3) When animals die, the carbon compounds present in them gets decomposed in the soil. These carbon compounds are taken in by the plants from the soil as nutrients.
