| Term | Definition |
|---|---|
| herbivore | a heterotroph that only eats plants |
| carnivore | a consumer that eats mostly or only amimals |
| omnivore | an organism that feeds off of both plants and animals |
| biome | a large region of Earth's surface that contains similar ecosystems and climate characteristics |
| biotic factor | a living part of an environment, including living organisms and the materials, such as bones, and leaves that comes from those organisms |
| abiotic factor | a nonliving part of an environment, including water, soil, light, air and other physical conditions that affect living organims |
| adaptaion | a variation that helps an organism survive and reproduce |
| behavioral adaptation | an action or activity that helps an organism survive and reproduce; like migration or hybernation |
| biosphere | all of the living things on Earth and the environments in which they live |
| climate | an area's long-term weather patterns |
| commensalism | a symbiotic relationship in which one species benefits and the other species receives neither harm nor benefit |
| community | the population of different species that interact with each other in an ecosystem |
| competition | when two or more organisms depend on the same limited resources for survival |
| conservation | the protection and careful use of natural resources |
| consumer | an organism that cannot make its own food, a heterotroph |
| deciduous forest | a biome in climates with annual warm and cold seasons. It is dominated by tree species that lose their leaves in winter |
| decomposer | a bacterium or fungus that breaks down waste materials from organisms and the remains of dead organisms |
| desert | a biome that receives very little rain. Temperatures can be very hot during the day and very cold at night. Much of the soil is bare |
| ecology | the study of how the living and nonliving parts of ecosystems work together |
| ecosystem | communities of living organisms and the abiotic factors that affect those communities |
| endangered species | a species that may soon become extinct or die out, due to habitat loss, overhunting, or other factor |
| energy pyramid | a diagram that shows how much energy is available to organisms at each level of a food web |
| estuary | wherever a river or stream meets the ocean, causing the saltiness of the water to vary |
| extinction | the loss of the last individual of a species |
| food web | a network of food chains that shows many of the ways in which food energy moves through a community |
| food chain | a simple model that shows how energy flows from one organism to another in a community |
| freshwater biome | a biome that includes both the flowing water of rivers and streams and the still water of lakes and ponds |
| grassland | a biome that is hot and dry in summer and cold and wet in the winter. It receives less rainfall than a forest but more than a desert |
| habitat | the part of the environment in which an organism lives |
| host | the organism that is harmed in parasitsm |
| limiting factor | any resource that limits the size of a population |
| marine biome | a saltwater biome |
| mutualism | a symbiotic relationship in which both species benefit |
| niche | an organism's role in its habitat. It includes the food an organism eats, the way it finds food, and the way it finds or builds shelter. No two species have exactly the same niche. |
| organism | a living thing |
| parasite | the organism that benefits in parasitism |
| parasitism | a symbiotic relationship in which one species benefits and the other is harmed |
| permafrost | a layer of permanently frozen soil found in the tundra |
| population | individual organisms of the same species living in the same area at the same time |
| predator | an organism that hunts and eats other animals |
| prey | an animal that is hunted |
| producer | an organism that makes its own food. Autotrophs include green plants, algae and some bacteria |
| salinity | the saltiness of ocean water. Salinity varies from place to place in the ocean. |
| scavenger | a consumer that eats dead animals |
| species | a group of similar organisms that can mate to produce offspring like themselves. |
| physical adaptations | a body structure that helps an organism survive and reproduce; for example gills help fish live in water. |
| symbiosis | a close relationship between two or more species |
| symbiotic | a kind of relationship in which species interact very closely with one another |
| taiga | a biome that includes coniferous trees, such as fir, spruce, pine, and cedar. Most precipitation is in the form of snowfall. |
| tropical rainforest | a biome found in warm regions with heavy rainfall. It has lush plant growth and many different plant and animal species |
| biodiversity | the number and variety of organisms in a given area during a specific time period |
| tundra | a cold and snowy biome with very few trees and a layer of permanently frozen soil called permafrost |
