Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
If secondary consumers are removed from the ecosystem, an ecological imbalance may be created. Secondary consumers are generally feed on other animals (primary consumers) Thus, on removing secondary consumers from food chain, there will be increase in population of primary consumers as a result all the grass and other vegetation will be eaten by the primary consumers. This will leads to desertification and eventually all the top consumers will also eliminated from the ecosystem.
