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.
