Ecology Terms
| Term | Definition |
|---|---|
| Ecosystem | all of the abiotic factors and biotic factors interacting in a specific area |
| Abiotic Factors | all of the non-living factors Examples: rocks, water, temperature |
| Biotic Factors | all of the living or once alive factors Examples: plants, animals, fungus |
| Producer | an organism that collects sunlight and creates its own food through photosynthesis Example: cactus |
| Consumer | an organism that gets energy from eating other organisms Example: mountain lion |
| Herbivore | an organism that eats only plants Example: desert tortoise |
| Carnivore | an organism that eats only other animals Example: rattlesnake |
| Omnivore | an organism that eats both plants and animals Example: black bear |
| Scavenger | an organism that eats already dead animals Example: vultures |
| Decomposer | an organism that gets its energy by breaking down dead plants and animals Example: Bacteria |
| Food Chain | an diagram that shows how energy flows from one producer through a single line of consumers |
| Primary Consumer | first consumer in the food chain |
| Secondary Consumer | second consumer in the food chain |
| Tertiary Consumer | last consumer in the food chain, top predator |
| Food Web | a diagram that shows how energy passes from many organisms, producers and consumers |
| Energy Pyramid | a diagram that shows the amount of energy that passes to each level of the food chain |
| 3 states of matter | solid, liquid, and gas |
| Water Cycle | a diagram that shows how water cycles on our planet |
| Precipitation | when water falls from the sky examples: rain, snow, sleet, hail |
| Evaporation | when water changes to gas |
| Condensation | when water vapor becomes liquid *how clouds are made |
| Transpiration | when water evaporates from plant leaves |
| Carbon Cycle | a diagram that shows how carbon cycles on our planet |
| Respiration | when organisms take in oxygen and release carbon dioxide gas |
| Combustion | when industries take in oxygen and release carbon dioxide gas |
| Photosynthesis | when plants take in carbon dioxide and release oxygen gas |
| Decomposition | when decomposers take in oxygen and release carbon dioxide when they break down dead organisms |
| Biome | large areas around the world that have the same temperatures and plants Examples: Desert, Tundra, Rainforest |
| Community | many different populations in one area example: owls, bluebirds, and squirrels living in the same tree |
| Population | a group of organisms of the same species or kind example: group of killer whales |
| Organism | one living thing |
| Habitat | an area that supplies an organism with everything it needs such as shelter, food, water, and a niche |
| Niche | a job or role an organism has in its environment example: bacteria bread down dead material |
| Predator | an animal that hunts organisms |
| Prey | an animal hunted by a predator |
| Biodiversity | the amount of different kinds of organisms in an ecosystem high biodiversity=stable ecosystem |
| Limiting Factors | any factor that limits the growth of a population of organisms |
| Carrying Capacity | the number of organisms an ecosystem can support |
| Habitat Loss | when habitat is destroyed by natural reasons or people |
| Invasive species | organisms that are not native to the ecosystem |
| Natural Resources | resources that are taken from nature, not man-made Examples: minerals, water, sunlight, wind, heat |
