Any form of life
A group of individuals of the same species found in a given area or located in the same area at a given time
A group of individuals of living organisms that interact with one another in an ecosystem
A group of living organisms that interact with one another and the non living physical environment as one unit
Geographic region of Earth that is inhabited by a community of distinct types of pland and associated animal species
A layer of soil, water, and air that sustains life
The levels of which 10% of energy is transferred from producer to consumer to secodary consumer to tertiary consumer.
Any organism that absorbs sunlight and in the process of photosynthesis creates its own energy.
A consumer that eats or consumes the producer and recieves 10% of the energy that the producer made.
An organism that eats or consumes the primary consumer and recieves 1% of the original 100% energy
An organism that consumes or eats the secondary consumer and recieves .1% of the original 100% energy.
A rainforest is a diverse forest that happens to rain almost everyday.
An example of an area that is a temperate deciduous forest is Pennsylvania.
The biggest desert in the world is the Sahara Desert in Africa.
The tundra is most commonly known as the place where polar bears live.
Grasslands and savannah are just about everywhere to some extent.
An example of a freshwater biome would be a freshwater stream.
An example of a marine biome is the ocean.
Biodiversity is important b/c without it ecosystems and habitats could be destroyed by a single thing like a specific disease.
abiotic factors are factors that aren't living such as water, air, and soil.
Biotic factors are factors that are living such as plants and animals.
Hot spots are the places on Earth that are the most biodivers and are where more than half of the organisms on Earth live.
Ecological Succession is a process in which a place that is struck with a disaster brings itself back to its previous state.
Primary Succession occurs in areas where an ecosystem never existed such as on bedrock.
Secondary Succession occurs in areas where an ecosystem previously existed and there is still some soil such as after a small landslide
A Climax community is the final stage of succession where there is a healthy amount of biodiversity and trees are now think and tall.
These are biotic or abiotic things that occur and cause a population to stay at a certain size. In other words they prevent a population from continuously growing.
Carrying capacity is the maximum amount of a species that an ecosystem can support.
Population growth is the the growth of a population.
The black plague was a point in time where a disease occured in Europe and killed roughly 2/3 of the human population in Europe and drastically depleated the world's population.
The industrial revolution was a point in time where in America many technological advances were taking place.
Exponential growth is an unsteady growth where the more there is the faster they populate.
The ability for a population to keep itself thriving, and growing.
Population growth in which the growth rate decreases with increasing number of individuals until it becomes zero when the population reaches a maximum.
A J-curve in growth represents exponential growth where limiting factors do not take place.
A S-curve is growth of a population where limiting factors occur then the population grows yet again.
Population growth rate is how fast or slow a population grows.
Water pollution is the contamination of water.
Point source water pollution is when water pollution occurs from from specific point.
Non- point source water pollution is when the pollution occurs from multiple different places.
any geological formation containing or conducting ground water, especially one that supplies the water for wells, springs, etc.
