#2 Producers make up more biomass than primary consumers because: Select one: a. only 10% of the energy at each trophic level is passed on to the next level. b. they do not eat anything. c. pound for pound, plant sugars are heavier than fat. d. both primary and secondary consumers eat grass.
Do you have any ideas?
I have no idea actually kinda suck at science:/
Ah, that's too bad 1.) B. This is because photosynthesis uses carbon dioxide, water, and sunlight to make ATP, and cellular respiration uses oxygen and glucose to make to make ATP
yeah lol :/ Thank you though!
No problem 2.) I want to say A, because there's not as much energy to store the farther up the trophic level you go
okay thanks! how bout these : #3 Generally speaking, the maximum number of links in a food chain is: Select one: a. 3 b. 5 c. 7 d. 9
I want to say A, because you have the producer, the primary consumer, and then the secondary consumer
Awsome Which of the following geometric shapes best represents the change in energy and change in biomass from one trophic level to the next? Select one: a. pyramid b. dodecahedron c. sphere d. parabola
#4 For most ecosystems, the ultimate source of energy is: Select one: a. plants. b. producers. c. the sun. d. water. This one would be C?
Any ideas? This one is fairly simple
You are correct on 4 3 is pretty simple. Which shape starts out wide, and then narrows into a point?
a ? pyramid
Yep, A would be correct
Thanks=) ! Couple more if your up to it ?
Sure thing ^_^
Which of the following would be one way a farmer could increase the amount of available nitrogen in his fields without adding a synthetic fertilizer? Select one: a. Grow a legume crop to support the development of root nodules b. Flush the field with water c. Burn unwanted plants on the field d. Add nitrogen gas to the fields
Do you have any ideas?
mmm Maybe I'd Pick B but thats just a guess
Actually, growing legumes and other similar plants restores nitrogen into the soil
oh okay lol i was way off thanks !
No problem ^_^
The diagram shows that currently about 100 gigatons/year of carbon are moved from the atmosphere to vegetation on land. Which process could decrease this number? Select one: a. Reducing the amount of urban area in the world b. Cutting down large areas of forests c. Warming up the oceans d. Increasing respiration rates
This one i have no ideas lol
B would be correct. If there was less trees, there would be less vegetation to absorb CO2
Which of the following processes would convert inorganic phosphorus in a rock to an organic form of phosphorus? Select one: a. Weathering b. Combustion c. Decay of dead animals d. Plant uptake
