Characteristics of Life
The difference between eukaryotic & prokaryotic
What is eukaryotic has a true nucleus and membrane bound organelles and prokaryotic has free floating DNA and no membrane bound organelles?
TRUE OR FALSE:
Two or more species cannot share the same niche
What is true?
Snow, sleet, hail, and rain
What are examples of precipitation?
What is the number of major land biomes?
6
The theory that existing life forms have evolved from earlier forms over long periods of time.
What is evolution?
The levels of organization from smallest to largest
What is cell, tissue, organ, organ system, organism?
What do all of these organisms have in common?
What is they are herbivores?
This is released during combustion, respiration, and decomposition
What is carbon dioxide?
This humid biome is located between the tropics and along the equator and is home to the most numerous types of plants and animals
What is a tropical rainforest?
Any kind of inherited trait that improves an organisms' chances of survival and reproduction in a given environment.
What is an adaptation?
The difference between an Autotroph & Heterotroph
What is auto makes own energy and hetero must eat other organisms for energy?
The energy roles
What are produces, consumers, and decomposers?
This must occur before plants may use nitrogen
What is nitrogen fixation?
This biome is located in the far north, but does not get much snow
What is tundra?
The process where organisms with advantages survive and pass their genes onto their offspring
What is natural selection?
The 3 statements of Cell Theory.
What are
1. living things are made up of one or more cells
2. all cells come from pre-existing cells
3. the cell is the basic unit of life

What are commensalism, mutualism, and parasitism?
This process is how plants change carbon dioxide to oxygen and other molecules
What is photosynthesis?
This biome has much diversity and trees that lose their leaves in winter
Evolution can only occur if this is involved
What is genetic variation?
All 9 characteristics of life
What are response to surroundings, grow and develop, reproduce, acquire and use energy, move, contain genetic information, one or more cells, levels of organization, ability to evolve?
The 10% rule
What is when only 10% of energy is passed onto the next trophic level?
This is the only way that nitrogen can enter back into the atmosphere
What is bacteria (denitrification)?
This biome usually gets 25-75 centimeters of rain. Fires and droughts are common
What is a grassland?
An example of a structure that is homologous to a cat's paw.
