Question

Your job is to raise jellyfish for aquariums (a very difficult task). You have ten jellyfish - five males and five females. EACH individual female jellyfish can produce 10,000 eggs per week and all your jellyfish are breeding. Unfortunately, only 10% of offspring survive through the end of the week (the rest die). What is the r for your jellyfish?

1) 50
2) 100
3) 500
4) 1000
5) 5000
6) 10,000

Answer 1

The r value, or intrinsic rate of increase, for the jellyfish population is 10,000. The growth rate (r) of the jellyfish population is 5,000, determined by the number of surviving offspring each week.

Step-by-step explanation:

The r value, or intrinsic rate of increase, represents the rate at which a population grows in ideal conditions. In this case, we have 10 female jellyfish that can each produce 10,000 eggs per week. However, only 10% of the offspring survive. To calculate the r value, we can multiply the number of females by the number of offspring they produce and then multiply that by the survival rate:

r = (10 females) * (10,000 eggs per week) * (10% survival rate)

r = 10,000

Therefore, the r value for the jellyfish population is 10,000. So, the correct answer is 6) 10,000.

The growth rate (r) of the jellyfish population is 5,000, determined by the number of surviving offspring each week.

Your question is about determining the growth rate (r) for your population of jellyfish given certain details about their reproduction. To find the growth rate (r), we need to multiply the number of female jellyfish by their egg production rate, and then by the survival rate of the offspring. Since you have 5 females, and each can produce 10,000 eggs per week, the total egg production would be 5 * 10,000 = 50,000 eggs per week. Considering that only 10% of these survive, we have 10% of 50,000 which equals 5,000 surviving offspring per week. This means that your jellyfish population’s growth rate (r) is 5,000.
