Across
- 3. The process by which cells break down molecules to release the energy they contain, process is not 100% efficient so considerable energy is lost from the ecosystem in the form of heat. (11)
- 5. Organism that obtains energy by eating only plants (9)
- 6. __________ of Energy: Diagram that shows the relative amounts of energy passing through each trophic level in a food chain or food web per year (7)
- 8. Series of steps in an ecosystem in which organisms transfer energy and matter by eating and being eaten (4, 5)
- 10. The passage of energy through the components of an ecosystem (6, 4)
- 11. A measure of the total organic compound mass (usually estimated by the dry mass) of organisms within a particular region (7)
- 12. Organism that relies on other organisms for its energy and food supply; also called a heterotroph (8)
- 14. Organism that can capture energy from sunlight or chemicals and use it to produce food from inorganic compounds; also called an autotroph (8)
- 16. Type of consumer that feeds directly on producers (7)
Down
- 1. Organism that obtains energy by eating both plants and animals (8)
- 2. Type of consumer that eats secondary or higher level consumers. (8)
- 4. Each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy. (7, 5)
- 7. Process by which green plants (and some other organisms) use light energy to convert water and carbon dioxide into high-energy carbohydrates such as sugars and starches. (14)
- 9. Network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem (4, 3)
- 13. Type of consumer that eats primary consumers. (9)
- 15. Organism that obtains energy by eating recently killed animals (9)
