Ecology

4. Abiotic factors are the non-living parts of an environment (e.g., sunlight, temperature, water). Bionic factors are the living parts of an environment
7. Environmental conditions that restrictions the growth, abundance, or distribution of an organism or a population in a specific ecosystem.
8. A state of equilibrium within an ecosystem where the various components and processes are stable and interact harmoniously.
10. An animal that hunts and feeds on other animals.
11. The maximum population size of a species that an environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
12. An organism that breaks down dead or decaying organisms.
14. In ecology, the approximate amount of energy that is transferred from one tropic level to the next.
16. A system of interlocking and interdependent food chains.
17. The natural home or environment of an animal, plant, or other organism.
19. The interaction between organisms or species in which both are harmed.

1. An organism that produces its own food through photosynthesis or chemo synthesis.
2. A species that is not native to a specific ecosystem and whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
3. The variety of life in the world or in a particular habitat or ecosystem.
5. The total mass of organisms in a given area or volume.
6. An animal that is hunted and killed by another for food.
9. The movement of energy from one object or substance to another.
13. A graphical model showing the flow of energy from one tropic level to the next in an ecosystem.
15. A biological community of interacting organisms and their physical environment.
18. A series of organisms each dependent on the next as a source of food.
20. The hierarchical levels in a food chain, comprising organisms that occupy the same position in a food chain.
