Answer:
0.1
Explanation:
To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.
In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.
Eukaryotic cells are cells that have a nucleus, while prokaryotic cells do not.
For the answer to the question above,
<span>The only taxon in which the biological characteristics are clearly identifiable is the <em><u>"species".</u></em></span>
The answer in agriculture.
<span>In agriculture, fertilizers are commonly used. But when they reach the bay, they could be cause of escessive nutrients. </span><span>Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This will lead to the death of aquatic animals that depend on oxygen.</span>
