Question

Ecology questions for final exam (Practice). Just the answers for now are fine but will ask questions depending on the answer. THANK YOU. Covid-19 has made learning difficult.

16. Competition has a negative effect on the individual's fitness via its negative effect on survival, growth, fecundity a. True b. False 90-94 Age 25-29 Questions 17 - 21 are based on the graph to the right. This graph describes the age structure of a population 100+ 95-99 17. The fraction of the youngest age class is a. The largest in the population 85-89 80-84 b. The smallest in the population 75-79 C. Larger than that of middle age classes (30 - 60 70-74 65-69 years old) 60-64 d. Smaller than that of middle age classes (30 - 60 55-59 years old) 18. The fraction of old (>80) females is a. Larger than the fraction of old males b. Equal to the fraction of old males 20-24 C. Smaller than the fraction of old males 15-19 19. What does it mean 10-14 5-9 a. That females have higher longevity b. That males have higher longevity 6 c. That females have higher fecundity d. That males have higher fecundity e. That males and females have the same longevity Male 20. What does it indicate regarding the general age of the population a. It is a relatively young population b. It is a relatively middle-aged population C. It is a relatively old population 21. What does it suggest regarding the growth pattern of the population a. Population grows exponentially b. Population stable C. Population is declining 04 5 4 3 1 2 3 4 5 6 2 1 0 Population Key Female The DMWC have given Telly data on a cohort of 97 snuffles trapped and radio-tagged that was followed for 10 years. Here is what he came up with

Answer 1

i can help you with Q16- 21

q16) true because competition leads to reduced survival rates, low fecundity and slow growth rate.

Q17) smaller than that of the middle age classes (evident from the bar length of the graph)

Q18) larger than the frcation of old males.

Q19) Females have higher longevity, hence more in number than males in the specific age group.

Q20) It is a relatively middle aged population as more no. of individuals lie in the age group 20-59

Q21) Population grows exponentially as there are more people in the reproductive age group.
