The acronym we use to remember the elements typically found in organic compounds.
What is CHNOPS?
100
This type of energy is greatest right before a falling object reaches the ground.
What is kinetic energy?
100
The observed process of change in the species structure of an ecological community over time after a catastrophic event such as fire, flood, or avalanche.
What is ecological succession?
100
This organelle has stacks of green pigment called chlorophyll that transform radiant energy into chemical energy.
What is the chloroplast?
100
The area of land where all of the water that is under it or drains off of it goes into the same place.
What is a watershed?
200
The trophic level responsible for converting radiant energy to chemical energy through the process of photosynthesis.
What are producers?
200
Words like standing, sitting, and holding all indicate that none of this was done.
What is work?
200
The degree of variation of life; the genetic variation, species variation, or ecosystem variation within an area, biome, or planet
What is biodiversity?
200
This organelle converts chemical energy into a form the cell can use.
What is a mitochondria?
200
The water located beneath the earth's surface in soil, pore spaces and in the fractures of rock formations.
What is groundwater?
300
The element that must be present in a compound for it to even be considered organic.
What is carbon?
300
You can tell if an object changes it motion by looking for this on the graph.
What is a change in the shape of the line segments?
300
The first organisms to 'reappear' after a forest fire or the clearing of forest.
What are weeds and small plants?
300
This organelle stores excess water, food, and waste for the cell.
What is a vacuole?
300
The excess water from rain and other sources that flows over the land.
What is surface water (run-off)?
400
The only organisms that have all arrows going away from them in a food web.
What are producers?
400
This is the place where there is an equal amount of potential and kinetic energies.
What is the half-way point (middle) of its motion.
400
The ability to maintain ecological processes over long periods of time; it is dependent on biodiversity.
What is sustainability?
400
All cells come from pre-existing cells.
All living things are made of cells.
The cell is the basic unit of life.
What is the Cell Theory?
400
Turning the water off while you brush your teeth and only allowing people to water their yards on certain days of the week.
What is water conservation?
500
CHNOPS are symbols that represent these elements that can be found in organic compounds.
What is carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur?
500
On a speed versus time graph, what kind of motion does a straight, flat line represent?
What is constant speed?
500
The greater number of these in a food web, the more sustainable the ecosystem.
What are number of organisms in the food web?
500
The correct order of organization found within an organism from least to most complex.
What is cell, tissue, organ, organ system, organism?
500
Fertilizers, pesticides, oil spills, construction, and leaking waste water are examples of ways humans do this.
