describe the cycling of matter and flow of energy through food webs, including the roles of the Sun, producers, consumers, and decomposers; and
A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
identify and illustrate how living organisms depend on each other through food chains.
create and describe food chains identifying producers and consumers to demonstrate how animals depend on other living things; and
identify and describe the flow of energy in a food chain and predict how changes in a food chain such as removal of frogs from a pond or bees from a field affect the ecosystem;
describe the cycling of matter and flow of energy through food webs, including the roles of the Sun, producers, consumers, and decomposers; and
Patterns are regular sequences that can be found throughout nature.
Patterns in the flow of energy and cycling of matter from producers to consumers and decomposers can be seen in a food web.
A system is a whole made of parts that work together. It has components and boundaries. It can interact with or be part of other systems.
The arrows in a food web illustrate the relationships among organisms (parts) and how matter is cycled and energy flows through the ecosystem (system).
Matter and energy are conserved, changing forms but maintaining quantities. Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes.
A food web models how energy flows between and among the organisms in an ecosystem. Energy flows into the system from the Sun to producers and then to consumers and decomposers. Energy flows from one organism to another through the consumption of matter.
