6th Grade level Ecology
| Question | Answer |
|---|---|
| Symbiosis | A close relationship between two different species living together. |
| Mutualism | A relationship where both organisms benefit. |
| Commensalism | A relationship where one organism benefits and the other is not helped or harmed. |
| Parasitism | A relationship where one organism benefits while the other is harmed. |
| Predation | An interaction where one organism hunts, kills, and eats another. |
| Competition | When organisms compete for the same limited resources. |
| Predator | An organism that hunts and eats another organism. |
| Prey | An organism that is hunted and eaten by a predator. |
| Parasite | An organism that benefits by living on or inside another organism. |
| Host | The organism that a parasite lives on or inside. |
| Organism | Any individual living thing. |
| Species | A group of similar organisms that can reproduce with one another. |
| Population | All members of the same species living in one area. |
| Community | All the different populations living and interacting in an area. |
| Ecosystem | All the living and nonliving things interacting in an area. |
| Habitat | The place where an organism lives. |
| Niche | The role or job an organism has in its ecosystem. |
| Biotic Factor | A living or once-living part of an ecosystem. |
| Abiotic Factor | A nonliving part of an ecosystem, such as water, sunlight, or temperature. |
| Resource | Something an organism needs to survive, such as food, water, or shelter. |
| Food Chain | A sequence showing how energy passes from one organism to another. |
| Food Web | A group of connected food chains in an ecosystem. |
| Producer | An organism that makes its own food, usually using sunlight. |
| Consumer | An organism that gets energy by eating other organisms. |
| Decomposer | An organism that breaks down dead organisms and waste. |
| Herbivore | A consumer that eats mostly plants. |
| Carnivore | A consumer that eats other animals. |
| Omnivore | A consumer that eats both plants and animals. |
| Scavenger | An animal that feeds on organisms that are already dead. |
| Adaptation | A trait or behavior that helps an organism survive and reproduce. |
| Camouflage | An adaptation that helps an organism blend into its surroundings. |
| Mimicry | An adaptation where an organism looks or acts like another organism. |
| Survival | Staying alive despite challenges in the environment. |
| Limiting Factor | Something that restricts how large a population can grow. |
| Carrying Capacity | The largest population an environment can support over time. |
| Pollination | The movement of pollen that allows flowering plants to reproduce. |
| Pollinator | An animal that carries pollen from one flower to another. |
| Invasive Species | A nonnative species that spreads and can harm an ecosystem. |
| Native Species | A species that naturally occurs in a particular area. |
| Biodiversity | The variety of living organisms found in an area. |
| Tick | A parasite that feeds on the blood of animals or humans. |
| Tapeworm | A parasite that can live inside the digestive system of its host. |
| Flea | A small parasite that feeds on the blood of its host. |
| Mosquito | An organism whose females can feed on the blood of other animals. |
| Clownfish & Sea Anemone | An example of mutualism because both organisms can benefit. |
| Bee & Flower | Mutualism: the bee gets food while the flower gets pollinated. |
| Oxpecker & Large Mammal | Often used as an example of mutualism because the bird gets food by eating parasites from the mammal. |
| Barnacle & Whale | A common example of commensalism because the barnacle gets transportation while the whale is generally unaffected. |
| Remora & Shark | A common example of commensalism because the remora gets food scraps and transportation. |
| Tick & Dog | Parasitism: the tick gets food while the dog is harmed. |
| Tapeworm & Human | Parasitism: the tapeworm gets nutrients while harming its human host. |
| Flea & Cat | Parasitism: the flea gets blood while the cat is harmed. |
| Lion & Zebra | Predation: the lion hunts the zebra for food. |
| Owl & Mouse | Predation: the owl hunts and eats the mouse. |
| Spider & Fly | Predation: the spider captures and eats the fly. |
| Hawk & Rabbit | Predation: the hawk hunts the rabbit for food. |
| Two Deer Fighting for Food | An example of competition because both organisms need the same resource. |
| Trees Competing for Sunlight | An example of competition because both plants need sunlight to survive. |
| + / + | Represents mutualism because both organisms benefit. |
| - / 0 | Represents commensalism because one benefits and the other is unaffected. |
| + / − | Can represent parasitism or predation because one benefits while the other is harmed. |
| Energy | What organisms need to carry out life processes. |
| Sunlight | The main source of energy for most ecosystems. |
| Shelter | A place that provides an organism protection from danger or weather. |
| Cooperation | When organisms work together in a way that helps them survive. |
| Environmental Change | A change in an ecosystem that can affect the organisms living there. |
| Population Change | An increase or decrease in the number of organisms in a population. |
| Ecological Relationship | Any interaction between organisms living in an ecosystem. |
