Populations have evolved complex interdependence with other populations and with the physical environment. CA Science Content Standards Grade 1 2a Different plants and animals inhabit different kinds of environments and have external features that help them thrive in different kinds of places. Grade 4 2a Plants are the primary source of matter and energy entering most food chains. 2c Decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals.
Students know that living organisms are composed of just a few elements.
Investigation 11 - Draw a small piece of campus and list its major biotic and abiotic factors, being as descriptive as possible. Then develop a Food Web using a diagram similar to Figure 11.2. Investigation 11 will form the focus for today's class, but we will spend LESS time naming the species. Instead, we will work toward a justification for some recommendations for the CSUF Master Development Plan. The first hour of class will be spent at one site on campus, making observations and collecting specimens.
