Ecosystems, Energy Movement, and Human Impacts on Climate

Where does all of the energy on Earth originally come?

• The sun

• The moon

• Consumers

• Eagles

Producers go through a process to turn radiant energy into chemical energy. This process is called

• cellular respiration

• translation

• competition

• photosynthesis

Which trophic level has the MOST energy available?

• producers

• tertiary consumers

• higher-order consumers

• secondary consumers

Both plants AND animals break down glucose to release the chemical energy inside. This process is called:

• photosynthesis

• cellular respiration

• translation

• transcription

Herbivores consume:
