A female moth lays nearly 150 eggs. In on year there may live up to five generations. Each larva eats about 20mg of wool. Assume that 2/3 of the eggs die and that 50% of the remaining moths are females. Estimate the amount of wool that may be destroyed b the descendants of one female within a year. (The first female belongs to the first generation

To estimate the amount of wool that may be destroyed by the descendants of one female moth within a year, we need to break down the problem into steps and make some assumptions.

Step 1: Calculate the number of eggs that survive:
If a female moth lays nearly 150 eggs and 2/3 of the eggs die, then 1/3 of the eggs will survive. Therefore, the number of eggs that survive is (1/3) * 150 = 50 eggs.

Step 2: Calculate the number of female moths from the surviving eggs:
If 50% of the surviving moths are females, then the number of female moths is (50% of 50) = 25 moths.

Step 3: Calculate the number of wool-eating larvae from each female moth:
Each larva eats about 20mg of wool, so the total amount of wool that may be destroyed by the descendants of one female moth is (20mg * 25 moths) = 500mg of wool.

Step 4: Estimate the amount of wool destroyed by multiple generations:
Given that there can be up to five generations within a year, we need to estimate the total amount of wool destroyed across all generations. Assuming each generation follows the same pattern, the total amount of wool destroyed will be: (500mg of wool * 5 generations) = 2500mg of wool.

Therefore, the descendants of one female moth may destroy approximately 2500mg (or 2.5 grams) of wool within a year.

Keep in mind that this is just an estimate based on the assumptions provided. The actual amount of wool destroyed may vary depending on factors such as the environment, availability of food, and natural enemies of the moths.
