all the organisms in a community plus abiotic factors

Question 3

Answer 3

energy
matter

Question 4

ecosystems are____

Answer 4

self sustaining

Question 5

what is needed for a self sustaining ecosystem

Answer 5

capture of energy
transfer of energy
cycle of nutrients

Question 6

what is inputed into an ecosystem

Answer 6

energy

Question 7

energy ____ through the ecosystem

Answer 7

flows

Question 8

where does matter cycling happen

Answer 8

within the ecosystem

Question 9

where does nutrients cycle happen

Answer 9

nutrients cycle through the ecosystem/ within the biosphere

Question 10

ecosystem inputs

Answer 10

energy
nutrient

Question 11

how does energy flow through the ecosystems (food chain)

Answer 11

sun will hit the producers ( plants) which are autotrophs then the primary consumers ( herbivores which are heterotrophs who will eat he plant and take some to the energy the sun gave the plant through photosynthesis and rest of the energy will be let out as heat. same when the secondary consumers eat the primary consumers but they would get less energy from the plant then the primary consumer and a lot of the energy will be released by heat again

Question 12

generalized nutrient cycle process

Answer 12

geological processes will help let out some chemicals and material and the abiotic reservoir take nutrients from non-living things and stores chemicals that can be used for cycling nutrients. some of the abiotic reservoir will enter the cycle and the nutrients will enter the food chain and it will be available for producers. producers will then give to consumers and they will decompose and the “nutrients” may go back to the abiotic resivor

Question 13

decompostion

Answer 13

connects all trophic levels

Question 14

primary production

Answer 14

amount of light energy converted to chemical energy by autotrophs is going to be available to the rest of the system

Question 15

primary production ex. sun energy for photosynthesis

Answer 15

sun energy is used for photosynthesis so how much of the sun’s energy will be available for the entire cycle

Question 16

ecosystem energy budgets

Answer 16

amount of energy that will be available for the rest of the system

Question 17

what sets the spending limit for an ecosystem’s energy budget

Answer 17

photosynthetic production

Question 18

what limits the photosynthetic otuput

Answer 18

solar radiation

Question 19

why does the sun give such little energy for the ecosystem

Answer 19

only some light hits photosynthetic plant and only some of them is at a usable wavelength

Question 20

which is more limiting to the ecosystem in the water
nutrients or lights

Answer 20

Nutrients

Question 21

both nutrients and light limits what specifically

Answer 21

limits primary production

Question 22

depth of light in the water means what

Answer 22

how far or how deep light can penetrate the water for photosynthesis

Question 23

limiting nutrients means

Answer 23

there needs to be certain elements for there to be more production of plants mainly in a certain area

Question 24

what are the 2 most limiting nutrients/elements

Answer 24

nitrogen and phosphorus

Question 25

what is upwelling of nutrient-rich waters

Answer 25

its when the water brings up the nutrients to the top of the ocean which contributes to more production of plants on the upper parts of ocean

Question 26

the high region of primary production leads to

Answer 26

ecological impacts

Question 27

due to the sewage upwelling terrible water to the top there was a lot of species loss because of

Answer 27

overgrowth of certain species

Question 28

the main affects on primary production

Answer 28

temperature and moisture

Question 29

there is more production of the primarys when

Answer 29

there is more moisture

Question 30

actual evapotranspiration

Answer 30

water transpired by plants and evaporated from a landscape

water gets pushed up roots and stems and water vapor comes through leaves its like the leaf is sweating

Question 31

what affects actual evapotranpiration

Answer 31

praciptaion
temprature
solar energy
and its related to the net primary production

Question 32

what two soil nutrients are a limiting factor in primary production

Answer 32

nitrogen and phosphorus

Question 33

how do adaptions help plants

Answer 33

help plants by accessing limiting nutrient from soil

Question 34

diffrent type of adaptions can be

Answer 34

mutualism
roots
enzymes

Question 35

why have mutualism with nitrogen-fixing bacteria

Answer 35

to access more nitrogen

Question 36

why have mutualism with mycorrhizal fungi and plant roots

Answer 36

fungi will increase surface area of roots and help get more nutrients

Question 37

why do roots have root hair

Answer 37

increase the surface area of roots

Question 38

how are enzymes a good adaptations

Answer 38

certain adaptions can give enzymes that increase the availability of limiting nutrients

Question 39

when an ecosystem is being affected by a loss of nutrients overtime plants will

Answer 39

gain adaptions that will help with selection within their ecosystem

Question 40

how much energy is lost on waste

Answer 40

50%

Question 41

how much energy is lost from cellular resperation

Answer 41

33%

Question 42

how much is lost threouhg growth not just for the next trophic lvl but through heat

Answer 42

17%

Question 43

after 5% there

Answer 43

isnt energy left from a certian trophic lvl

Question 44

meat that we eat is not affective cause

Answer 44

barley any amount of photosynthetic energy in it for us

Question 45

restoration so they
