Question | Answer |
---|---|
Ecosystem | Is an area whose communities are determined by the environmental conditions of the area. For example, Michigan contains soil conditions with amounts of rainfall per year creating forests, wetlands, ponds, and lakes, among others. |
Biotic Components | All the living components of an ecosystem like plants and animals. |
Abiotic Components | All the non-living components of an ecosystem, like air, rock, and water. |
Population | A group of organisms of the same species living in a particular area at a particular time. Can include plant or animal examples. |
Community | Consists of populations or organisms living in a general area. This could include urban examples such as squirrels, bird populations, trees and other plants. |
Producers | Obtain food by trapping light energy to make food and supply their energy needs. Plants are examples of these. |
Consumers | Meet their energy needs by eating other organisms or their products. All animals, including humans are examples of these. |
Decomposers | Use dead organisms or their products to meet their energy needs. Examples are bacteria and fungi. |
Bacteria | An example of a decomposer, these are simple one-celled organisms that thrive by living on or in other organisms. |
Fungus | Plant-like organisms that lack chlorophyll and must use plants and animals as well as animal waste products as their food source. |
Parasite | Organisms that get its food by living on or in the body of another organism. |
Predator | An organism that kills and eats another organism. |
Prey | Organism that is killed and eaten by another organism. |
Symbiosis | A relationship between two different species living in close association with one another. |
Competition | When species compete for habitat space, food, or water in a given area. |
Pollution | Release of harmful materials into the environment. |
Resource Depletion | When there is not enough of a needed resource such as space in a habitat, water, or food. |
Species Extinction | A group of species that look alike and reproduce among each other that no longer exist. |
Niche | The role of an organism in an ecosystem. |
Source of Energy | In a food chain or web, the Sun's energy moves through a community from producer to consumer. |
Habitat | The place where an organism lives. For example, the chorus frog lives in the scattered ponds of the Blacklands. |
Food Web | Shows the relationship between all the species in a community. |
Balance in Ecosystems | Refers to communities interacting with each other equally to maintain a healthy community and population of species. |
Environmental Impact | Everything that surrounds an organism and acts upon it. |
Climate Change | A change in the average weather pattern of a region. |
Forests | A biome with many kinds of trees keep or lose their leaves during changes in climate. Has a long growing season followed by a winter. |
Wetlands | An abundance of precipitation yield plant and animal life that can withstand large volumes of water with poor soil drainage. |
Ponds | Small freshwater ecosystem containing various wildlife such as fish and plants. |
Lakes | Freshwater ecosystems containing a wide range of wildlife. Examples are Huron, Superior, Ontario, Erie, and Michigan. |
Tropical Rainforest | Found near the equator, climate is hot all year round with 200-460 cm of rain each year. Greatest degree of diversity of any biome. |
Tundra | Located in the high northern latitudes, climate is very cold, harsh, with long winters, short and cool summers. Soil is nutrient poor with a permafrost layer a few inches down. |
Desert | Located midlatitude, the climate is generally very hot during the day and cool and night. Less than 4 cm of rain per year. Often rich in minerals. |
Coral Reef | Saltwater biome home to an abundance of corals, fish and sponges. Very fragile and endangered biomes. |
Dunes | Very hot locations mid latitude with mountainous amounts of minerals. |
Prairies | A type of grassland, this type of biome is found in the mild temperate zones of the United States and Ukraine. These grasslands are covered with wheat, corn, and oats. |
Herbivore | A type of consumer that eats only plants, like a cow. |
