| 14804012613 | laws that are very important in environmental science | two laws of thermodynamics | 0 | |
| 14804016164 | 1 law of thermodynamics | matter and energy cannot be destroyed but energy can be transformed but energy goes from highly organized to less organized | 1 | |
| 14804027534 | highly organized energy vs less organized | highly- more useful ex. coal less- less useful ex. ashes heat/ light energy is lost | 2 | |
| 14804045171 | 2 law of thermodynamics | as energy is transformed it goes from highly organized to less organized so as energy floes through an ecosystem, some energy is lost in each step, specifically the path of energy (see picture) | 3 | |
| 14804068591 | path of energy | sun (LE), plants (autotrophs),--photosynthesis-- glucose (chemical energy), animals (hetereotrophs) | 4 | |
| 14804083319 | total glucose made | gross primary productivity | 5 | |
| 14804094053 | the glucose left over after plants use what they need for movement, growth, and reproduction | net primary productivity and this is used by animals (heterotrophs) | 6 | |
| 14804104453 | equation for photosynthesis | 6CO2 (carbon dioxide) + 6H2O (water) +LE-------> C6H12O6 (glucose) + 6O2 (oxygen) | 7 | |
| 14804140032 | equation for cellular respiration- turning glucose into a more readily used form of ATP | C6H12O6 (glucose) + 6O2 (oxygen)-------> 6CO2 (carbon dioxide) + 6H2O (water) + ATP | 8 | |
| 14804162594 | different ecosystems | differ in levels of productivity due to limiting factors ex. deserts lack water ex. tundras lack heat ex. tropical rainforest has high productivity because it has no limiting factors like water or heat | 9 | |
| 14804189100 | as energy passes through an ecosystem it moves through | different trophic levels to create food webs |  | 10 |
| 14804201584 | 1 level of food web | producers - all food webs must have this level bc - it supports all levels -usually plants in a terrestrial ecosystem and phytoplankton in an aquatic ecosystem | 11 | |
| 14804214879 | 2 level of food web | primary consumers -hetereotrophs -herbivores or omnivores (when eating plants) | 12 | |
| 14804226091 | 3 level of food web | secondary consumers -heterotrops that eat primary consumers -carnivores or omnivores (when eating meat) | 13 | |
| 14804241851 | 4 level of food web | 3 and 4 level consumers -third level eats secondary level -fourth level eats third level -all either carnivores or omnivores | 14 | |
| 14804259666 | 5 level of food web | decomposers a. scavengers -dead organisms eaten ex. vultures, crabs b. dentrivores -eat parts of an organism/waste ex. dung beetles and worms c. decomposers -convert organisms back to SPONCH elements ex. fungi and bacteria | 15 | |
| 14804448147 | limit to the number of tropic levels | there are usually no more than 5 levels bc each level loses so much energy because they do cellular respiration to make ATP | 16 | |
| 14804460496 | how most energy is lost | heat | 17 | |
| 14804468053 | amount of energy available to the next | 10% | 18 | |
| 14804476845 | how energy relationship can be shown | energy pyramid, this can be shown in terms of levels of consumers and individuals which is why top predators are more rare |  | 19 |
