1. Option C

2. Option C

3. Option B

Explanation:

1. The common food of hair-streak (Strymon melinus) is fruits and flowers of  clover, buckwheat, pea family , mallow species and several other plants. If in case the entire clover plantation is removed from this location, it is for sure that the larva of hair streak will face deficiency of food in the area and thus its survival would become difficult and thus the population of hair-streak would go down

2. Black bears in Chattahoochee Forest are found only in those areas where food is available, once the food get exhausted they move to a new place. In this way black bears are a population  Eliminate as where ever they go they consume/destroy the food and leave nothing for other species to feed themselves and survive.

3.

The population is decreased or slowed down by all limiting factors. Hence, here all abiotic and biotic factor hat causes a population’s size to slow or decrease is a limiting  Eliminate factor

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
