Unit 1
The main product of photosynthesis
What is glucose?
A type of species that thrives in a variety of conditons
What is a Generalist?
A species with low growth rate that causes species population to increase slowly until it levels out around carrying capacity
What is a K-selected species?
The innermost layer of the Earth's interior
What is the core?
A method of harvesting trees that involves removing most, or all of the trees within an area
What is clear-cutting?
A model of how energy and matter move through food chains
What is a food web?
The number of different species in a given area
What is species richness?
The limit to a number of individuals that can be supported by an existing habitat or ecosystem (K)
What is carrying capacity?
The outermost layer of the Earth (includes upper mantle and crust)
What is the lithosphere?
When a shared resource becomes depleted because it is unregulated
What is Tragedy of the Commons?
Plants, algae, and some bacteria that use the Sun's energy to produce usable forms of energy (ex. glucose)
What is a producer?
A species that is not very abundant but has a large effect on its ecological community
What is a keystone species?
When a population becomes larger than the environments carrying capacity
What is overshoot?
An area below the ocean where tectonic plates move away from each other
What is a divergent boundary?
A mining technique that creates a large pit or hole in the ground
What is open-pit mining?
An idea that talks about the amount of energy passed through each trophic level
What is the 10% rule?
When a large population declines in number, the amount of genetic diversity carried by the surviving individuals is greatly reduced
What is population bottleneck?
A pattern of survival over time in which there is low survivorship early in life, with few individuals reaching adulthood
What is a Type III survivorship curve?
The process in which an oceanic plate moves under a continental plate and pushed towards the center of the Earth
What is subduction?
An area surrounding a well that does not contain ground water
What is the cone of depression?
The process by which cells convert glucose into energy in the absence of oxygen
What is anaerobic respiration?
The process of speciation that occurs with geographic isolation
What is allopatric speciation?
An method that allows you to find a population's doubling time by dividing 70 by a population's growth rate
What is the rule of 70?
A layer of the atmosphere closet to the surface of Earth
What is the troposphere?
The removal of overlying vegetation, soil, and rock to expose underlying ore
What is strip mining?
