Question

4. In a hypothetical ecosystem, the different trophic levels are occupied by the following organisms
Producer: Grass
Primary consumer: Grasshopper
Secondary consumer: Frogslf the grasshopper population declines, what will most likely happen to the grass population
Decrease
Fluctuate
Increase
Remain constant​

Answer 1

Answer:

Increase

Explanation:

This is because frogs will continue feeding to the declining population of grasshopper there will be decreased dependent on grass due to the declining population of grasshoppers thereby leading to increase in grass.

Answer 2

Answer:

The grass population increases with a decrease in the grasshopper population, under the given conditions.

Explanation:

Here, we are given that Grasses serve as producers, while the primary consumers are grasshoppers, and the secondary consumers, frogs.

Now, we are also told that the grasshopper population is declining. This means that there are less grasshoppers to feed on the constantly growing grass, and thus, the population of the grass will increase uncontrollably. The frogs don’t feed directly on grass, either, to keep the grass in check.

So, as a consequence of an imbalance in the food chain, the population of grass increases uncontrollably.
