Answer:
1,000 kcal
Explanation:
As a general rule, every trophic level only gains 10% of the energy from the trophic level.
So, the grass has 100,000 kcal of energy. Assuming the bird eats grass, it only gets 10,000 kcal of energy. Assuming the fox eats the bird, it only gains 1,000 kcal of energy.
A virus<span> is a small </span>infectious agent<span> that </span>replicates<span> only inside the living </span>cells<span> of other </span>organisms<span>. Viruses can infect all types of </span>life forms<span>, from </span>animals<span> and </span>plants<span> to </span>microorganisms<span>, including </span>bacteria<span> and </span><span>archaea
</span>While not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles. These viral particles<span>, also known as </span>virions<span>, consist of two or three parts: (i) the </span>genetic material<span> made from either </span>DNA<span> or </span>RNA<span>, long </span>molecules<span> that carry genetic information; (ii) a </span>protein<span> coat, called the </span>capsid<span>, which surrounds and protects the genetic material; and in some cases (iii) an </span>envelope<span> of </span>lipids<span> that surrounds the protein coat when they are outside a cell. The shapes of these virus particles range from simple </span>helical<span> and </span>icosahedral<span> forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an </span>optical microscope<span>. The average virion is about one one-hundredth the size of the average </span>bacterium<span>.</span>
