A. Living things all share basic needs for life.
B. Living organisms acquire the energy they need for life processes through various metabolic pathways (photosynthesis and cellular respiration).
C. Matter and energy are recycled through cycles such as the carbon cycle.

Item Type(s):
This benchmark may be assessed using:
MC
item(s)
Also Assesses - Clarification :
Students will explain that living systems obey the Law of Conservation of Mass and the Law of Conservation of Energy.
Students will describe and/or explain the general processes of photosynthesis or cellular respiration.
Students will describe how matter and energy are transferred in the carbon cycle.
Students will describe the role of light, carbon dioxide, water, and/or chlorophyll in the process and products of photosynthesis. - Content Limits :
Items will not address or assess the stages of photosynthesis or cellular respiration.
Items may not assess the interrelatedness of photosynthesis and cellular respiration.
Items will not use the term reactant.
Items will not use the term ATP.
Items will not assess the function of organelles related to the processes of cellular respiration or photosynthesis.
Items will not assess anaerobic respiration.
Items referring to the carbon cycle may include carbon reservoirs, such as the atmosphere, organisms, fossil fuels, sediments, and oceans/water. - Stimulus Attributes :
Scenarios may use word equations for photosynthesis or cellular respiration; chemical equations may not be used. - Response Attributes :
None specified - Prior Knowledge :
Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.3.L.17.2, SC.4.L.17.2, and SC.4.L.17.3.
SC.8.L.18.1 Describe and investigate the process of photosynthesis, such as the roles of light, carbon dioxide, water and chlorophyll; production of food; release of oxygen.
SC.8.L.18.2 Describe and investigate how cellular respiration breaks down food to provide energy and releases carbon dioxide.
SC.8.L.18.3 Construct a scientific model of the carbon cycle to show how matter and energy are continuously transferred within and between organisms and their physical environment.
- Test Item #: Sample Item 1
