All Flashcards
What is an adaptation?
A heritable genetic variation that increases an organism's fitness.
Define natural selection.
The process where heritable variations lead to differential reproductive success.
What are invasive species?
Non-native species that disrupt ecosystems, often lacking natural predators.
What are anthropogenic impacts?
Human-caused changes to the environment, such as habitat destruction and pollution.
Define intraspecific competition.
Competition for resources within the same species.
Define interspecific competition.
Competition for resources between different species.
What are the four principles of natural selection (VIND)?
Variation, Inheritance, Natural Selection (Differential Survival), Differential Reproduction.
What are the differences between adaptation and acclimation?
Adaptation: Genetic changes over generations. | Acclimation: Short-term physiological adjustment.
What are the differences between intraspecific and interspecific competition?
Intraspecific: Competition within a species. | Interspecific: Competition between different species.
What is the difference between natural and anthropogenic disruptions?
Natural disruptions: Caused by natural events like floods or fires. | Anthropogenic disruptions: Caused by human activities like pollution or habitat destruction.
