Ecosystems

Question 1

Does a polymer in a plant remain the same polymer in an animal when it eats the plant?

Answer 1

Those polymers get turned into monomers during digestion and during biosynthesis those monomers turn into whatever polymers the cells need to respirate

Question 2

Does a monomer in a plant stay the same monomer when eaten by an animal?

Answer 2

It can remain the same if that monomer is needed for biosynthesis or it could be converted to a different monomer

Question 3

Overall do polymers/monomers stay the same

Answer 3

Polymers will always change however monomers may stay the same

Question 4

If a c atom from a plant or animal is consumed by another animal is it a c atom it’s entire existence?

Answer 4

Yes. matter cannot be created not destroyed.

Question 5

Does chemical energy in the bonds of molecules stay as chemical energy?

Answer 5

No, energy originally enters the plant as light energy then transformed into chemical energy which is then released as heat

Question 6

When a decomposer grows on a dead tree, does it return the molecules to the ground as those same molecules?

Answer 6

It would only stay the same if a part of the plants falls off and becomes detritus. Otherwise, Decomposers will digest the materials and rearrange the molecules into what they need and/or respire those molecules

Question 7

Do decomposers recycle some atoms from dead things back to producers?

Answer 7

Yes because atoms do not change

Question 8

Do decomposers return the energy found in the bonds of the molecules of the dead things they are decomposing back to the ground?

Answer 8

No because the energy found in the cc ch bonds will end up being released at heat

Question 9

Are carbon atoms able to leave the ecosystem they are in? Can they be reused?

Answer 9

Yes CO2 in atmosphere can travel in and out of ecosystems. Respired CO2 can be used during photosynthesis to make glucose.

Question 10

Can energy leave the ecosystem it is in? Can it be reused?

Answer 10

It can leave as heat but cannot be reused

Question 11

What’s the populations sizes of prey v predators?

Answer 11

There will always be more prey than predators

Question 12

Movement of inorganic and organic material?

Answer 12

Photosynthesis brings in inorganic CO2 in organic sugars

Question 13

Why isn’t all the matter than an herbivore consumes available to carnivores?

Answer 13

Because herbivores respirate Co2 and H2O which may enter the atmosphere. They also defecate matter.

Question 14

What is the only way for the matter in carnivores to return to an ecosystem

Answer 14

They could respirate which a plant om could use for photosynthesis. They could also defecate/ die and decomposers would use that matter

Question 15

Does all of the matter in a trophic level (herbivore/omnivore) get consumed by the next?

Answer 15

No because some organisms camouflage, release toxins, or flee.

Question 16

What happens in digestion

Answer 16

Polymers turn into monomers

Question 17

Biosynthesis

Answer 17

Monomers turn into polymers

Question 18

Do atoms kn molecules that make up plants ever just atoms?

Answer 18

No, chnops are always apart of a compound

Question 19

How does energy move through ecosystems

Answer 19

Light energy is captured by plants and transformed into chemical energy, chen energy transfers within organisms during biosynthesis, moves from organisms during eating, digestion, and biosynthesis. Eventually will be released as heat

Question 20

What is the only way for decomposers to get energy from dead things?

Answer 20

They must digest it and absorb it so they can have useful forms of chemical energy

Question 21

When organisms die, are plants able to reclaim the energy from the ground?

Answer 21

No because decomposers release the energy into heat

Question 22

Do plants respire greater than they photosynthesize?

Answer 22

No because during the day they photosynthesize more than they respirate but they only do respiration during the night so they match in the ens

Question 23

What do decomposers do with detritus

Answer 23

They respire it

Question 24

How does energy flow and carbon cycle?

Answer 24

Carbon enters as CO2 in a plant and either moves from plant to animals, dies, or the cells respire. Decomposers/animals will respire and release CO2 which could enter back into the plant

Energy enters a plant as light energy then transformed into chemical energy in cc ch bonds they will be released as heat when respired
