03.1 Test (Curriculum)

Gerald is studying the plants and animals of a meadow. He classifies the grasses and clover as _______________ because they make their own food through the process of (chemosynthesis /decomposition / photosynthesis / regurgitation). He classifies insects that feed on the clover as (carnivores / detritivores / herbivores / omnivores) because he thinks they eat only plant matter, not animal matter.

• autotrophs
• consumers
• decomposers
• heterotrophs

Scientists classify clams as consumers. Which observation about clams provides the strongest evidence for this classification?

• Young clams are able to move from place to place.
• Clams gain energy and nutrients by filtering particles from the water.
• Clams use calcium compounds to make a hard shell.
• Clams live on the ocean floor, and sometimes survive without sunlight.
