Climate

• Earth’s tilt on its axis, combined with its revolution around the sun, plays a major role in determining the climate of a given location.
• Other factors, such as latitude, temperature, precipitation, topography, elevation, and human actions can also influence climate.

Terrestrial, Marine and Freshwater Ecosystems

• Ecosystems can be large or small, terrestrial or aquatic.
• Ecosystems are dynamic, experiencing shifts in population composition and abundance and changes in the physical environment over time, which ultimately affects the stability and resilience of the entire system.

Physical and BehavioralCharacteristics that enable organisms to survive

• Organisms possess physical characteristics and behaviors that enable them to survive in their environment and obtain resources to meet basic needs and carry out life processes, increasing their chances of survival.

You should:
• compare terrestrial (land), marine (saltwater), and freshwater ecosystems
• know how adaptations - structural (physical) and behaviorial - enable organisms to survive in an ecosystem
