Questions and Answers

What is the main point of the text?

  • Organisms adapt to both their environment and the organisms around them (correct)
  • Organisms do not adapt at all
  • Organisms adapt only to the organisms around them
  • Organisms adapt only to their environment

Why is it important for organisms to adapt to the organisms around them?

  • To prevent competition for resources
  • To dominate other species
  • To ensure survival in the environment
  • To maintain balance and coexistence within the ecosystem (correct)

What happens if an organism can't adapt to its environment?

  • It will dominate the environment
  • It will become the apex predator
  • It will not survive (correct)
  • It will force other organisms to adapt

Study Notes

Impact of Introduced Species on Ecosystems

  • An introduced species is a species living outside its native environment due to human activity
  • If not adapted to the environment, it will die; survival depends on competition and predation
  • Successful introduction can lead to breeding and impact on other organisms in the ecosystem
  • Introduced species can compete with native species, alter grazing patterns, and affect predator/prey dynamics
  • Grazing patterns may change if the introduced species is an herbivore
  • Competition for resources like water and sunlight occurs if the introduced species is a plant
  • Introduction of a large predator into an ecosystem without native large predators can have far-reaching impacts
  • The effects of an introduced species on other organisms can have a domino effect
  • Local extinction of native species is likely when an introduced species becomes established
  • History provides examples of introduced species causing extinction or near extinction of native species
  • Invasive species threaten or cause the extinction of native species and dominate landscapes
  • Native species may not have adaptations to defend against introduced species, leading to harm in non-native environments
