5. A protozoan population lives in the gut of termites and digests the wood the termite eats. Some of the byproducts of this process provide food for the termite. What type of symbiotic relationship is this? 6. What is an organism's niche? 7. How are decomposers important to an ecosystem? 8. What factors distinguish one type of biome from another? 9. Why aren't there clear-cut boundaries between biomes? 10. Why are there few, if any, trees in the tundra biome? 11. With all the lush vegetation found in the tropical rain forest biome, one would think that the soil would be rich in organic matter. Why is this not the case? 12. Why is the marine biome the most stable of all biomes?
