A koala must eat 200 grams of leaves each day to survive. The trees in a area can provide 1380 g of leaves per day what is the maximum number of koalas that can survive in the area

6 koalas

Explanation:

The maximum number of koalas that can survive in the area is 6.

Each koala must eat 200 grams of leaves per day.

The trees in an area can provide a total of 1380 g of leaves per day.

The maximum number of koalas that can survive in this area would be the total amount of leaves production per day divided by the amount of leaves required by each koala per day.

Hence:

Number of koala the area can support = 1380/200 = 6.9

Remember that each koala must eat 200 grams per day, therefore, the maximum number of koala that can survive in the area approximately 6.

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.
