Standard 3.5

The student will investigate and understand relationships among organisms in aquatic and terrestrial food chains. Key concepts include
a)    producer, consumer, decomposer;
b)   herbivore, carnivore, omnivore; and
c)    predator and prey.

In order to meet this standard, it is expected that students will
·       differentiate between predators and prey.
·       distinguish among producers, consumers, herbivores, omnivores, carnivores, and decomposers.
·       infer that most food chains begin with a green plant.
·       identify sequences of feeding relationships in a food chain.
·       explain how a change in one part of a food chain might affect the rest of the food chain.
·       create and interpret a model of a food chain showing producers and consumers.

Standard 3.6

The student will investigate and understand that ecosystems support a diversity of plants and animals that share limited resources. Key concepts include
a)    aquatic ecosystems;
b)   terrestrial ecosystems;
c)    populations and communities; and
d)   the human role in conserving limited resources.

In order to meet this standard, it is expected that students will
·       describe major water-related ecosystems and examples of animals and plants that live in each.
·       describe major dry-land ecosystems and examples of animals and plants that live in each.
·       compare and contrast water-related and dry-land ecosystems.
·       explain how animals and plants use resources in their ecosystem.
·       distinguish between a population and a community.
·       predict what would occur if a population in a specific ecosystem was to die.
·       analyze models or diagrams of different water-related ecosystems in order to describe the community         of organisms each contains and interpret how the organisms use the resources in that ecosystem.
·       analyze models or diagrams of different dry-land ecosystems in order to describe the community of             organisms each contains and interpret how the organisms use the resources in that ecosystem.
·       list ways that humans can help conserve limited resources.
