A. It can exist without a constant source of energy input
B. It must contain consumers but can exist without producers.
C. It involves interactions between biotic and abiotic factors.
D. It can exist on land, but it cannot exist in lakes, rivers, or oceans.
The correct statement is C. that an ecosystem involves interactions between biotic and abiotic factors.
Biotic factors are the living things in an ecosytem, they include plants, animals, bacteria, fungi and others. Abiotic factors on the other hand, are the non-living factors in an ecosystem, they include water and air, sunlight, the amount precipitation in an ecosystem is also an example of abiotic factor. The two types of factors are crucial for an ecosystem to exist and thrive.

4. Which pathway represents the flow of electrons during photosynthesis? (1 point) A.) H2O > Photosystem I > Photosystem I

Yuki888 [10]

Answer:

4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D. $H_{2}O$ > <em>NADP </em>> <em>Calvin cycle.</em>

Electron is first provided to the photo-system II by the phtolysis of water.
Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome $b_{6}f$ .
Finally, electron from the photo-system II is used to reduce NADP to NADPH.
NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.

5. The correct answer is B.) photosynthesis.

Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
In light independent phase of photosynthesis, it requires ATP and NADPH in order to synthesize food.
Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.
