Cycle of Matter
This cycle continuously moves water between the atmosphere, land, oceans, and living things
The Water Cycle
An organism that eats both plants and animals is called a:
Omnivore
This is the organelle found in both plant and animal cells where most of the chemical reactions of cellular respiration occur.
Mitochondrion or Mitochondria
Cells use this element — found in soil and converted by bacteria — to build important life molecules including DNA and proteins.
What is Nitrogen?
In the tropical rainforest food web studied in class, this top predator fed on monkeys, iguanas, and tapirs.
Jaguar
These are the three starting materials, or reactants, that a plant cell must have available in order for photosynthesis to occur.
Carbon Dioxide, light energy, and water
In the carbon cycle, this biological process removes carbon dioxide from the atmosphere and locks it inside living organisms.
Photosynthesis
In an ecosystem where frogs eat insects and herons eat frogs — if the frog population suddenly disappeared, this is what would most likely happen to the insect population.
Increase
When one organism eats another, only approximately this percentage of energy is successfully passed on to the next level.
10% Energy
This human activity dramatically speeds up the release of carbon stored underground into the atmosphere.
"Combustion"
This type of organism always occupies the base of an energy pyramid because it contains the greatest amount of available energy.
During photosynthesis, the light energy absorbed by chloroplasts is converted into this type of energy, which is then stored in the bonds of sugar molecules.
Chemical Energy
This fundamental law of chemistry, demonstrated when you count the atoms on both sides of any chemical equation and find them equal, states that this is never created or destroyed during a reaction.
Conservation of matter
When wolves were removed from Yellowstone National Park, this population grew rapidly and began overgrazing plants along riverbanks.
The Elk population
Iff producers in an ecosystem contain 100,000 joules of energy, and only 10% is transferred at each level, this is the amount of energy available to a tertiary consumer.
