32. reduces surface tension

1. 35 degrees Celsius
2. an animal that only eats plants as its source of energy
3. water clings tightly to other water
5. trees that produce seed-bearing cones and have thin leaves shaped like needles
6. non-living chemical and physical factors in an environment
8. living components that affect an ecosystem
11. an organism that produces its own food and provides food for others
13. the study of how living things interact with each other and with their environment
17. an organism that eats both plants and animals
18. water clings tightly to other things
20. latin word for science
25. an organism that only eats insects
