Study Notes
Classification Tools
- The primary function of a dichotomous key is to identify and classify living organisms, such as plants or animals, by asking a series of questions about their characteristics.
Keystone Species
- Keystone species are important in an ecosystem because they have a disproportionate impact on their environment and play a crucial role in maintaining the structure and function of their ecosystem.
Predator-Prey Relationships
- A common characteristic of predator-prey relationships is that they are interconnected, with the population of one species affecting the population of the other.
Population Dynamics
- Emigration is the term that best describes the movement of individuals out of a population.
Environmental Conservation
- One positive impact humans can have on the environment is through conservation efforts, such as reducing pollution, preserving natural habitats, and promoting sustainable practices.
