Ecology | The study of the interactions between living organisms and the nonliving components in an ecosystem. |
Species | A class of organisms that have similar characteristics. |
Population | The number of specific species/type of organisms living in an area. |
Community | The different populations/species living together in a specific area. |
Biotic Factors | Living, or once living, organisms in an ecosystem. For example, a tree and a lion. |
Abiotic Factors | Nonliving components of an ecosystem that are essential for life. For example, water and sunlight. |
Producer | A plant that can make its own energy/food using sunlight. |
Consumer | An organism that must eat either a producer or another consumer in order to obtain energy/food. |
Decomposer | Breaks down down dead organisms (plant and animals). |
Food Chain | Shows one simple path of how energy can flow through an ecosystem. |
Food Web | Shows multiple paths/relationships where energy flows through an ecosystem. |
Limiting factor | A factor that can control the population. For example, if there is not enough water the populations would decrease. |
Energy Pyramid | Diagram that shows how energy moves through an ecosystem. |
Symbiotic Relationship | A relationship between two organisms in which both benefit, one benefits while the other is not harmed, or one benefits while the other is harmed. For example, a tick on a dog. |
Migrating | Move from one region or habitat to another. |

Herbivore | An animal that feeds on plants. |
Omnivore | An animal or person that eats food of both plant and animal origin. |
Carnivore | An animal that feeds on flesh. |
Mutualism | Both species benefits |
Commensalism | One species benefits, one species is not harmed |
Parasitism | One species benefits, one species is harmed. (Cuckoo) |
