An Invasive Species' population typically grows exponentially because there are no predators for that organism.


True

False

Answer 1

Here are the answers:

1. A Group of individuals... = Population

8. Total deer = 9 deer/mi² × 11 mi² = 99

9. Which graph shows Population Oscillations? — I can't see the images you attached. The correct choice is the graph that shows regular cyclic rises and falls (oscillating around a mean or carrying capacity). If you can re-upload or tell me which option number shows that pattern, I’ll pick it for you.

10. Emigration is the term for individuals moving into an area. = False (emigration = leaving; immigration = moving in)

11. Mortality rate refers to how many individuals were born in a certain area. = False (mortality = deaths; natality/birth rate = births)

12. Geographic dispersion types (select all): Clumped Dispersion; Uniform Dispersion; Random Dispersion

13. Abiotic limiting factors (select all): Water; Natural Disasters; Climate

14. A sharp increase in population is known as a 'population crash.' = False (a crash is a sharp decrease)

15. Zero growth rate indicates the population is remaining at a stable number. = True

16. Geographic DISTRIBUTION shows what regions of the world organisms are found in. = True

17. A graph with 2 y-axis and 1 x-axis is known as = Combination Graph (dual-axis graph)

18. Age Structure with predominantly older (post‑reproductive) individuals indicates = Diminishing or Declining Population

19. Reproductive strategies — matches:
- K-selected = produce few offspring, high parental investment, stable environments, populations near carrying capacity (K)
- r-selected = produce many offspring, low parental investment, exploit unstable environments, boom-and-bust dynamics

20. An invasive species' population typically grows exponentially because there are no predators for that organism. = True (usually true in the early phase when they lack predators/controls)

If you want, re-upload the four graph images for question 9 and I’ll pick the exact option.
