Answer:
<em>The correct option is A) The amount of grass will increase, and the number of frogs will decrease.</em>
Explanation:
As from the above illustration, we can see that the grasshoppers feed on grass. The frogs feed on the grasshoppers.
If most of the grasshoppers are killed, then the grass will have fewer organisms to feed on it. As a result, the amount of grass will increase.
Reduction in the population of grasshoppers will mean that there is lesser food available for the frogs. As a result, the frogs will compete for food. Most will migrate, others might get killed due to lack of food. Hence, the population of frogs will reduce.
Population density is the characteristics of a population increase with plentiful of resources. Population density is the measurement of every person in the population per unit area or unit volume. It is applied to a living organism and most of the time on humans. It is also the number of people living in each unit of area such as a square mile.
