Across
- 2. Organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil.
- 7. Logging The removal of trees without regard for environmental consequences, often leading to deforestation and habitat destruction.
- 10. A group of individuals of the same species living in a specific area.
- 14. A type of symbiosis where one organism benefits and the other is neither helped nor harmed.
- 15. The interaction between two species where one (the predator) hunts and eats the other (the prey).
- 16. The process by which metabolic waste products and other non-useful materials are eliminated from an organism.
- 18. A type of symbiosis where one organism (the parasite) benefits at the expense of the other (the host).
- 21. The process by which decomposers break down dead organisms and organic waste, releasing nutrients back into the ecosystem.
- 24. The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released into the atmosphere.
- 25. Web A complex network of interconnected food chains within an ecosystem.
- 26. Animals that eat both plants and other animals.
- 28. All the different species living together in a particular area, interacting with each other.
- 29. Consumer Predators that feed on secondary consumers, occupying the top trophic levels in a food chain.
- 30. The amount of water vapor present in the air.
Down
- 1. A mode of nutrition in which organisms, typically fungi or bacteria, obtain nutrients by decomposing dead organic matter.
- 3. A type of symbiosis where both organisms involved benefit from the relationship.
- 4. Animals that primarily eat plants.
- 5. The elimination of solid waste from the digestive system.
- 6. A biological community of interacting organisms and their physical environment.
- 8. Cycle The movement and exchange of organic and inorganic matter back into the production of living matter, such as the carbon and nitrogen cycles.
- 9. Organisms, typically plants and algae, that produce their own food through photosynthesis and form the base of the food chain.
- 11. Animals that primarily eat other animals.
- 12. The interaction between organisms or species that vie for the same resources in an ecosystem, such as food, space, or mates.
- 13. The metabolic process in which organisms convert oxygen and glucose into energy, carbon dioxide, and water.
- 17. Of Organisms The way in which different species are spread out across various ecosystems and geographic areas.
- 19. Erosion The displacement of the upper layer of soil, often due to wind, water, or human activity, leading to loss of soil fertility.
- 20. Chain A linear sequence of organisms where each is eaten by the next member in the chain.
- 22. Consumer Carnivores or omnivores that eat primary consumers.
- 23. A close and long-term biological interaction between two different biological organisms.
- 27. Consumer Herbivores that consume producers to obtain energy.
