This section of ecology focuses on the movement of energy through an ecosystem and the recycling of matter. In most cases, the energy for an ecosystem starts with the sun. Producers use this energy to make food using the process of photosynthesis. Consumers then eat producers, or other consumers, to get the energy they need. There are several types of consumers...herbivores, carnivores, omnivores, scavengers and decomposers. The decomposers break down waste and return nutrients to the soil.
Matter is recycled in an ecosystem. We will be learning about the water cycle, carbon cycle, nitrogen cycle and phosphorus cycle.

Ecology
We are currently studying the first of 2 units on ecology. Our first unit focuses on biotic and abiotic factors, limiting factors, biomes and niches. Below are some vusual flashcards to help you study. Scroll over to stop the slide show and advance at your own speed. A study guide and online flashcards can be found under "Important links" to the right.

Landforms
We have recently been studying landforms in class. To help us remember some key ideas, we sang the Landform Song. Check out these students' variations of the tune...

Erosion
Last week we started learning about weathering, erosion and deposition. Weathering is the process that breaks down rock and other material at Earth's surface. Erosion moves weathered material from one place to another. Deposition is the process where sediment is set down at a new location. (Go Team!)
Running water is the dominant process that shapes the landscape, including California's topography. We modeled erosion by rivers in class. Students were able to observe oxbow lakes, alluvial fans and deltas. Check out the pictures below.
