Aquatic fungus, swims around and water and get underneath or skins and affects their organ usage. |
|
|
The study of interactions among and between organisms and their abiotic environment |
Ecology |
|
|
Biotic |
Living environment, includes all organisms |
|
|

|
What does the biosphere include? |
Atmosphere hydrosphere lithosphere |
|
|
Energy |
The ability or capacity to do work |
|
|
Thermodynamics |
Study of energy and its transformations |
|
|
System |
Object being studied; set of things that function together; organs, SolarSystem, ecosystems, school systems |
|
|
How do you feedback loops occur ? |
Occurs when the output of a system serves as an input that also regulates the system |
|
|
Negative feedback |
The response of the system is often said that of the output |
|
|
Positive feedback |
Their sponsor the system is in the same direction of the output |
|
|
Positive feedback |
Their sponsor the system is in the same direction of the output |
|
|
First law of thermodynamics |
Energy cannot be created or destroyed; it can be changed from one form to another |
|
|
Second law of thermodynamics |
When energy is converted from one form to another, some of it is degraded to heat |
|
|
Photosynthesis |
Biological process by which energy from the sun is transformed into chemical energy of sugar molecules |
|
|
Cellular respiration |
The process where the chemical energy captured in photosynthesis is released within cells of the plants and animals |
|
|
Chemosynthesis |
The process by which energy produced from in organic raw material such as enzymes, hydrogen sulfide and oxygen; water in sulfur/sulfate are additional byproducts |
|
|
Energy flow |
Passage of the energy in a one-way direction through an ecosystem |
|
|
Energy flow |
Passage of the energy in a one-way direction through an ecosystem |
|
|
Detritivores |
Feed on detritus (partially decomposed organic matter, such as leaf litter and animal dung) |
|
|
Food chains |
Energy from food passes from one organism to another |
|
|
What do food webs represent |
Interlocking food chains I connect all organisms in an ecosystem |
|
|
Biomass |
Measure of the total amount of living material |
|
|
What are the three main types of ecological pyramids? |
Pyramid of numbers, pyramid of biomass, pyramid of energy |
|
|

|
|
Bacteria and Archae are both what? |
Prokaryotes |
|
|
Biological communities |
The organisms in a community are interdependent in a variety of ways. Species compete with one another for food, water, living space, and other resources. Some organisms kill and eat other organisms. Some species for an intimate associations with one another where as other species seem only distantly connected. |
|
|
Symbiosis |
An intimate relationship between members of two or more species |

|
What are the results of co-evolution? |
Interdependent evolution of two interacting species |
|
|
What are the three types of symbiosis? |
