Human Impacts
Define Human Impact
Changes to the biosphere. Ie: biodiversity, ecosystems, and natural resources. Caused directly or indirectly by Humans.
Where Is Carbon Found
Everywhere.
Define A Food Chain
A food chain has organisms that depends on the next to survive.
Define A Ecosystem
An ecosystem consists multiple species of fauna and flora living together in an environment.
Define Macro Molecules
A large molecule.
Name the #1 cause of global warming regarding Humans
Fossil Fuels.
Name all 4 reservoirs.
Hydrosphere, Geosphere, Atmosphere, and Biosphere.
Define A Food Web
A food web is a system of multiple species that shows the flow of energy from one species to another.
What is an Invasive species
An invasive species is an organism that outcompetes native species and drives them out.
Name all 4 Macro Molecules
Proteins. Lipids. Carbohydrates. Nucleic Acids.
What are the top 3 constraints for recovering nearly-extinct species?
Time, Money, and is it Realistic.
Name at least 3 ways carbon moves through Earth.
Respiration. Buried. Burned. Diffusion. Eaten. Oxidization. Photosynthesis. (+100 extra points if included all 7 ways)
In Order, bottom to top, name all of the layers of the Energy Pyramid.
Producers > Primary Consumer > Secondary Consumer > Tertiary Consumer. (If you include Decomposers you get +50 extra points.)
Define Keystone Species
A key stone species is an organism that has more of an impact on all other species in an ecosystem if it were to go extinct or rise rapidly in population.
Describe at least 2 functions for Macro Molecules.
Protein has structural properties and produces Enzymes. Carbohydrates act as quick energy and helps control blood sugar and insulin metabolism. Lipids are long lasting energy and help with moving and storing energy, they also absorb vitamins and make hormones. Nucleic Acids stores and expresses genetic information. (+100 extra points if you describe all 4 functions)
Define Eutrophication.
Eutrophication is when excessive nutrients and richness is inside a body of water, producing mass amounts of algae and death of marine life due to lack of oxygen.
Describe either Photosynthesis or Respiration, scientifically.
Respiration: A biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, and water. (+50 points if you include ATP)
Photosynthesis: Water, sunlight, and carbon dioxide combine to form glucose (sugars) and give off oxygen.
What is a model and how is it useful in science.
Models are 3D representations of small, large, or complex features of the natural world. Models helps us see what is happening with matter and energy in a biological system and helps explain things that can't be explained directly.
How does fire affect an ecosystem?
Fire acts as a "reset" by burning dead plants, making way for more life. Although, too much fire can do more harm than good.
What do Enzymes do, and name all the places where it takes place in the digestive system.
Enzymes help speed up chemical reactions by breaking down food. Your mouth has salivary glands which produce saliva containing enzymes. Your stomach also releases enzymes to help break down food. Small intestines release enzymes to help break down food. Your Pancreas produces all of the enzymes your body uses.
In order, name all of the conservation statuses.
Least Concern > Near Threatened > Vulnerable > Endangered > Critically Endangered
What is fire?
Fire isn't a solid, liquid, nor gas, or even plasma. It's a simple chemical reaction.
Name all 4 monomers, for all 4 macro molecules.
Carbohydrate's are Monosaccharides. Protein's is Amino Acids. Lipid's is Glycerol. Nucleic Acid's are Nucleotides.
