Chapter #13- PPT Notes
What is biodiversity? What 4 elements make up 99% of all species?
4 elements carbon, hydrogen, oxygen and nitrogen make up 99% of the mass of all living things . Earth organisms are composed about 23 of the 107 known chemical elements. Biodiversity is the diversity of the species.
What is photosynthesis?
Photosynthesis is the process in which carbon and oxygen gets absorbed by plants that by the sunlight will release them into CO2 or carbon dioxide ,which is what we breath and release as well.
Describe the flow of energy through systems. What is the main storage molecule of energy
in animals?
Sugar-molecules. Energy is degraded (that is transformed into a less useful form). Carbohydrates are the main stage molecule of energy in animals.
What is chemo synthesis? What source of energy is used instead of sunlight?
Is the process used by plants undersea. Hydrogen Sulfide, is the source of energy.
What is primary productivity a measure of?
is the synthesis of organic material is measured in grams of carbon bound into carbohydrates per meter of ocean surface are per year.
Why is productivity higher near the coasts of continents than in the open oceans?
There is more nutrients carried by the currents near them. As well there is a good productivity near the poles for the same reason.
