released into lakes and streams. Based on what you know about homeostasis, what
problems to wildlife might result from thermal pollution?
2. Based on your knowledge of the chemistry of living things, explain why is it important
to eat a balanced diet.

d. Reproduction
If the statement is true, write “TRUE.” If it is false, change the underlined word or words to
make the statement TRUE.
6. The process by which an organism puts food into its body is digestion.
7. Green plants produce energy from the sun during photosynthesis.
