classification
Across
- 2. In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche.
- 6. an intraspecific relationship in which one species (the commensal) obtains benefits such as food, shelter, or locomotion from another species (the host) without causing adverse effects.
- 8. Association between two different organisms wherein one benefits at the expense of the other.
- 9. the role an organism plays in a community
- 12. an organism that mostly feeds on plants.
- 14. a group of species that are commonly found together
- 17. a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life
- 20. the interaction of individuals that vie for a common resource that is in limited supply,
- 25. consists of all the food chains in a single ecosystem
- 26. a non-living part of an ecosystem that shapes its environment
- 27. an organism that regularly consumes a variety of material, including plants, animals, algae, and fungi.
Down
- 1. the interaction between two dissimilar organisms living in close physical association.
- 3. any kind of green plant
- 4. made up of the parts of Earth where life exists—all ecosystems
- 5. the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
- 6. organism on the food chain that depends on autotrophs (producers) or other consumers for food, nutrition, and energy.
- 7. a group of organisms that can reproduce with one another in nature and produce fertile offspring.
- 8. animals that are killed and eaten by other animals
- 10. All organisms in an ecosystem depend upon each other. If the population of one organism rises or falls, then this can affect the rest of the ecosystem.
- 11. the ecological process by which energy is transferred from living animal to living animal based on the behavior of a predator that captures and kills a prey before eating it
- 13. organism that breaks down dead organic material
- 15. a living organism that shapes its environment
- 16. group of organisms linked in order of the food they eat, from producers to consumers, and from prey, predators, scavengers, and decomposers.
- 18. transferred between organisms in food webs from producers to consumers.
- 19. a group of individuals of the same species living and interbreeding within a given area
- 20. mutually beneficial interactions that occur among individuals of the same species or between different species.
- 21. organisms that hunt and kill other organisms for food
- 22. an area classified according to the species that live in that location
- 23. a type of symbiotic relationship where all species involved benefit from their interactions.
- 24. an organism that mostly eats meat, or the flesh of animals.
