|
1. Ecology |
The study of the interactions among organisms and their environment. |
|
|
2. Biotic |
Living factors of an ecosystem.
|
|
|
3. Abiotic |
Non-living factors of an ecosystem (Water, light, temperature, etc). |
|
|
4. Autotroph
|
Make their own food (usually through photosynthesis). For example, plant and algae. |
|
|
5. Heterotroph |
Organisms that obtain their food from the environment. Types of heterotrophs include herbivores, carnivores, omnivores and saprobes. Examples of heterotrophs are animals, bacteria and fungi. |
|
|
6. Herbivore |
Animals that feed only on plants. |
|
|
7. Carnivore |
Animals that feed on other animals. This category is divided in predators and scavengers. |
|
|
8. Predator |
Feed on prey they kill. For example lions and wolfs. |
|
|
9. Scavenger |
Feed on dead animals they find. For example vultures. |
|
|
10. Omnivore |
Animal that feeds on both plant and animals. For example humans and bears. |
|
|
11. Decomposer |
Organisms that feed on dead plants and animals. For example fungi and bacteria. |
|
|
12. Symbiotic relationship
|
A relationship between two closely associated organisms in which at least one benefits.
|
|
|
13. Mutualism
|
Both organisms benefit. For example legumes and bacteria and termites and cellulose digesting microorganisms. |
|
|
14. Parasitism
|
One organism benefits while the other is harmed. For example tapeworm, flea, mistletoe. |
|
|
15. Commensalism |
One organism benefits while the other is not affected. For example clownfish and sea anemones and barnacles on a whale. |
|
|
16. Biosphere
|
It is the highest level of organization that ecologists study. |
|
|
17. Ecosystem |
It is a collection of all the organisms that live in a particular place, together with their nonliving, or physical, environment. |
|
|
18. Community |
Assemblages of different populations that live together in a defined area. |
|
|
19. Population |
Group of individuals that belong to the same species and live in the same area. |
|
|
20. Niche |
A niche is the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. |
|
|
21. Food chain
|
A series of organisms through which food energy is passed. |
|
|
22. Producer |
Autotrophs (produce organic from inorganic substances). |
|
|
23. Primary consumer |
Herbivores or omnivores. |
|
|
24. Secondary consumer
|
Carnivores or omnivores. |
|
|
25. Food web
|
Interconnected food chains. Different organisms are at different levels and there are many at each level. |
|
|
26. Biomagnification |
Each higher level of consumers accumulates large quantities of poisonous substances. |
