Any form of life
Populations of living organisms that interact with one another in an ecosystem
Group of individuals of the same species found in a given area or located in the same area ata given time
Population Growth Rate, Sustainability, Logistic Growth, S-Curve, Exponential Growth, J-Curve
A group of living organisms that interact with one another and the nonliving physical environment as one unit.
Geographic region of Earth that is inhabited by a community of distinct types of plants and associated animal species. Smiliar areas all over Earth
Temperate Deciduous Forest
Layer of soil, water, and air that sustains life. Ex: Earth is our biosphere.
Food chains show the wequence in whixh energy is transferred from one organism to the next as one eats the other.
Food webs show us what an ecosystem really looks like. Food Webs are really a whole bunch of food chains. They show us that organisms eat a lot more than jsut one thing.
The levels of comsumers, every level gets only 10% of what it eats.
Biodiversity is the degree of variation of life forms within a given ecosystem, biome, hotspots, or an entire planet. Biodiversity is a measure of the health of ecosystems. It consists of biotic and abiotic factors.
Any living thing that was once living or is living
Any non-living thing that isn't or never was alive
Ecological Succession means a process in which the communities of an ecosystem change over time
Primary Succession is the process of emergence of an ecosystem where it has never previously existed. Ex: sides of a volcano
Secondary Succession is the process that begins in an ecosystem when something has disturbed or destroyed the natural community. (Tornado)
Climax Community is a community that keeps a fairly constant number and variety of organisms for a long period of time; forms in the last stage of succession. ( Grasses in Prairies, Trees in forests)
Pioneer Species are the hardy species that establish itself at the start of te process of succession. Ex: mosses and lichens
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into bodies of water.
Point Source- pollution that comes from a single source, such as a factory or wastewater treatment plant.
Non-point Source- a large amount of water pollution does not come from a single point but from many different sources.
Aqulifer- body of permeable rock that can contain of transmit groundwater.
