Unit 7 - Ecology

This unit will look at the factors affecting the environment which will include abiotic and bitoic factors.
Nonliving factors of the environment including light, temperature, and atmospheric gases.
A living component of a community; for example organisms, such as plants and animals.
Biological diversity of an ecosystem, which is determined by the variety of species of plants and animals.
Use of organisms to clean up toxic waste.
Planting of a single plant species, such as corn or wheat, in a field.
Process in which a mining company restores land used during mining operations to its original contours and replants vegetation.
Global Warming
Rise in global temperatures, which may be due to increases in atmospheric carbon dioxide from deforestation and burning of fossil fuels - related to the greenhouse effect.
Koppen Climate
a system for classifying climates that is based on mean monthly and annual values of temp and precipitation.
Differential Heating
Unequal heating that occurs across earth's surface and when combined with the earth's rotation becomes the engine that drives earth's weather.
Thermal Expansion
An increase in the size of a substance when the temperature is increased
Sea Level Rise
Causes erosion of shorelines and rainforests, flooding of wetlands that house freshwater ecosystems. Caused by global climate changes that is melting sea ice
Overall weather in an area over a long period of time (usually 30 years)
Acid Rain
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.
A group of ecosystems that share similar climates and typical organisms
Moderate Climate
Biome near the equator with warm temperatures, wet weather, and lush plant growth
Biome in which the winters are cold but summers are mild enough to allow the ground to thaw
A tropical grassland biome with scattered individual trees, large herbivores, and three distinct seasons based primarily on rainfall, maintained by occasional fires and drought.
A scrubland biome of dense, spiny evergreen shrubs found at midlatitudes along coasts where cold ocean currents circulate offshore; characterized by mild, rainy winters and long, hot, dry summers.
An extremely cold, dry biome.
Invasive Species
An introduced species that spreads out and often has harmful ecological effects on other species or ecosystems
Exponential Growth
Growth of a population in an ideal, unlimited environment, represented by a J-shaped curve when population size is plotted over time. (rapid growth)
Carrying Capacity
Largest number of individuals of a population that a environment can support
A term that typically describes a species that no longer has any known living individuals.
Illegal hunting of protected animals
Exotic Species
organisms that are not native to a particular area
Genetic Variation
Differences among individuals in the composition of their genes or other DNA segments
Habitat Alteration
a change in the particular environment or place where organisms or species tend to live greatest cause of extinction
A group of organisms of the same species populating a given area.
A group of similar organisms that can breed and produce fertile offspring.
Place where an organism lives
a group of interdependent organisms inhabiting the same region and interacting with each other
A system formed by the interaction of a community of organisms with their physical environment
Limiting Factor
Any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms.
Ecological Footprint
A way of measuring how much of an impact a person or community has on the earth. Someone who uses more natural resources will have a bigger footprint than someone who uses less.
To decrease the amount of products purchased or produced with the intent of minimizing waste.
Involves using a resource over and over in the same form
The process of making new products from materials that were used in another product.
