Abiotic- nonliving Biotic- living |
Abiotic vs. Boitic |
|
|
Predators hunt and feed on other organism ( Prey ) |
Predator vs. Prey |
|
|
Parasites occupy or feed on another organism ( host ) Host organism is always harmed by the parasite |
Parasite vs. host |
|
|
Autotrophs are producers, organisms make their own food ( ex. Plants ) Hetertrophs are consumers, get nutrients by eating other organisms ( ex. animals, humans ) |
Autotroph vs. Hetertroph |
|
|
Mutualism- both organisms benefit eachother ( ex. bees and flowers ) Commensalism- one organisms benefits, the other is not affected ( ex. sharks and remora fish ) Parasitism- the parasite is benefiting by harming the host organism ( ex. ticks and dogs ) |
3 types of symbiotic relationships |
|
|
Species- is a group of the same organisms that interbreed Population- is all the individuals in a species in a certain area community- is all the populations that are present in an area Ecosystem- is all the abiotic and biotic components of a specific enviroment |
Species population, community, ecosystem |
|
|
Nutrients are constantly recycled in an ecosystem ( cycles ). Energy is transferred up trophic levels and is lost in the form of heat ( energy pyramid. |
How are the movements of energy and nutrients through ecosystems different? |
|
|
Herbivores only eat produces ( plants ) Carnivores only eat other animals ( meat-eaters) Omnivores eat plants and animals |
Different between herbivores, omnivores, and carnivores? |
|
|
Similarities and differences between photosynthesis and chemosynthesis? Photosynthesis is used by plants and algae, uses sunlight, water, and carbon dioxide. Chemosynthesis is performed by bacteria in hydrothermal vent communities, uses sulfur compounds, both produce starches/ sugars and release oxygen. |
Similarities and differences between photosynthesis and chemosynthesis? |
|
|
they live in the same habitat but occupy different niches ( roles ) in the habitat |
How can two similar species occupy the same habitat without competing with eachother? |
|
|
-Decomposers recycle and return nutrients to the enviroment, it keeps the ammount of matter fairly constant in an ecosystem. bacteria and fungi are decomposers -detritivores are known as scavengers, they eat dead animals biodiversity- lots of different plants and animals cows release methane which causes global warming |

|
|
Food chain shows a single organism at each trophic level. Food web shows all the interacting food chains in an ecosystem |
How is a food chain different than a food web? |
|
|
Quaternary consumers- 0.01%-5th trophic level Tertiary consumers-0.1%- 4th trophic level Secondary consumers-1%-3rd trophic level Primary consumers-10$-2nd trophic level Producers-100%1st trophic level |
