Across
- 2. the trophic level plants and other photosynthetic organisms belong to
- 6. organisms that can eat both plants and animals for food
- 9. the step of the water cycle during which water absorbs into the ground and gathers in underground reservoirs
- 10. a large underground water reservoir (hint - there is a really big on under the state of FL)
- 11. information about the world gathered through the senses
- 12. the form in which energy is lost to the environment as it passes from one trophic level to the next
- 14. type of microscope that produces a 3D light-based image
- 15. information obtained through observation used to support or reject a hypothesis
- 18. the type of succession that occurs in an ecosystem that experienced a sudden drop in biodiversity
- 20. type of limiting factors made of living things
- 21. the type of succession that occurs in a previously uninhabited area with no established nutrients
- 24. the largest carbon reservoir
- 27. the step of the water cycle that occurs when water evaporates from the tissues of plants
- 30. the percentage of energy that is passed from one trophic level to the next
- 31. a system of interdependent species based on energy transfer between trophic levels
- 32. the property of water that allows it to dissolve many substances easily
- 33. an organism that feeds on dead organic matter, recycling its trapped nutrients back into the environment
- 34. the step of the carbon cycle caused by burning fossil fuels
- 36. a negative side-effect of nonrenewable resources (can be in the air, water, or soil)
- 37. any non-native organism introduced to an ecosystem, usually via human activity, that causes disruption to the natural food web
Down
- 1. the type of bonds that hold water molecules together
- 3. organisms that must ingest other organisms for food
- 4. the sum of all licing organisms in an ecosystem (the higher this is = the better)
- 5. a predicted answer or explanation for the target question of a scientific investigation based on observations
- 7. this is what water molecules do when they freeze, causing ice to be less dense than liquid water.
- 8. the max population an ecosystem can support based on its limiting factors
- 13. the loss of individuals from a population to a new population
- 16. a group of individuals of the same species living and interbreeding within the same area
- 17. the biogeochemical cycle that includes photosynthesis, decomposition, and cellular respiration
- 18. type of microscope best used to see the outside details of something very microscopic
- 19. type of limiting factor made of nonliving things/resources
- 22. an explanation of phenomena in the world based on observations
- 23. the biogeochemical cycle that includes evaporation, precipitation, and runoff
- 25. the abiotic limiting factor of aquatic ecosystems that determines the amount of light available to the ecosystem
- 26. type of microscope that produces a 2D light-based image
- 28. the type of resources that naturally replenish at the same or faster rate than they are used
- 29. the addition of new individuals to a population from another population
- 35. an abiotic limiting factor of aquatic ecosystems that measures the amount of salt dissolved in the water
