Science: EALR 1 Systems, Content Standard 4-5 SYSA

Systems contain subsystems.


Science: EALR 1 Systems, Content Standard 4-5 SYSB

A system can do things that none of its subsystems can do by themselves.


Science: EALR 1 Systems, Content Standard 4-5 SYSC

Systems have inputs and outputs. Changes in inputs may change the outputs of a system.


Science: EALR 1 Systems, Content Standard 4-5 SYSD

One defective part can cause a subsystem to malfunction, which in turn will affect the system as a whole.


Science: EALR 4 Life Science, Content Standard 4-5 LS2A

An ecosystem includes all of the populations of living organisms and nonliving physical factors in a given area. Living organisms depend on one another and the nonliving physical factors in their ecosystem to help them survive.


Science: EALR 4 Life Science, Content Standard 4-5 LS2B

Plants make their own food using energy from the sun. Animals get food by eating plants and/or other animals that eat plants. Plants make it possible for animals to use the energy of sunlight.


Science: EALR 4 Life Science, Content Standard 4-5 LS2C

Plants and animals are related in food webs with producers (plants that make their own food), consumers (animals that eat producers and/or other animals), and decomposers (primarily bacteria and fungi) that break down wastes and dead organisms, and return nutrients to the soil.


Science: EALR 4 Life Science, Content Standard 4-5 LS2D

Ecosystems can change slowly or rapidly. Big changes over a short period of time can have a major impact on the ecosystem and the populations of plants and animals living there.


Science: EALR 4 Life Science, Content Standard 4-5 LS2E

All plants and animals change the ecosystem where they live. If this change reduces another organism's access to resources, that organism may move to another location or die.
