Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

The second one because they can indicate infection and sickness
Nitrogen is returned to the atmosphere during the nitrogen cycle in a process referred to as denitrification.
<h3>What is denitrification?</h3>
It is a process whereby nitrogen becomes mineralized from nitrogenous compounds. In other words, it is the reduction of nitrates to produce elemental nitrogen which is returned to the atmosphere.
Denitrification is a microorganisms-driven process. The nitrates are made to pass through a series of reactions with intermediate products before finally leading to the production of elemental nitrogen.
