The flow of energy in an ecosystem is best
melamori03 [73]
The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers. 

Explanation; 
Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem. Ecosystem maintain themselves by cycling energy and nutrients.
The energy from sunlight is taken up by producers which use it to produce organic compounds through photosynthesis. The energy is then passed successively to the trophic levels, that is from the producers to the consumers ( primary, secondary, tertiary and quotienary consumers). During this transfer some energy is lost at each trophic level in form of heat.

Which of the following factors is needed during light-dependent reactions to create ATP and NADPH energy molecules?
Alexeev081 [22]

Answer: The correct answer is- Solar energy, carbon dioxide, and water.

Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.

This phase occurs in the thylakoid membrane of chloroplast.

During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.

This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.

In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.

Thus, solar energy, carbon dioxide, and water is the right answer.
