How do living and nonliving parts of the Earth interact and affect the survival of organisms?
Biotic & Abiotic Factors
LEARNING OBJECTIVES:
1. Identify biotic and abiotic factors.
2. Identify the role of organisms in any ecosystem.
3. Analyze how limiting factors (biotic and abiotic) affect the size of a population.

Ecosystems
What are the characteristics of the major biomes of the world?
LEARNING OBJECTIVES:
1.Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature. (Reference #: SC.912.L.17.2)

Videos:
- Diving The Depths of Under Water Life
- The Secret Life of Plankton
Homework: Write about science!
- Choose three different aquatic ecosystems. For each of these ecosystems, select a plant and an animal, and explain how the organisms have adapted to their environments.
- Make it visual! Include drawings or pictures of the ecosystems and the organisms you selected.
Populations
What factors contribute to changes in populations?
Changes in population size are determined by births, deaths, immigration, emigration, density-dependent, or density-independent limiting factors (biotic or abiotic) determining the carrying capacity.

6.2_ Ecological Disturbances and Succession (Pages 182-185)
SC.912.L.17.4 Describe changes in ecosystems resulting from seasonal variations, climate change and succession.
How do ecosystems change overtime?
LEARNING OBJECTIVES:
1. Describe the potential changes to an ecosystem, resulting from seasonal variations, climate change, and/or succession.
2. Explain how ecosystems recover from a disturbance.
3. Compare primary and secondary succession.
