Answer:
Light energy or chemical energy
Explanation:
Light energy or chemical energy support the whole pyramid. Without it, plants/producers would die (they wouldn't be able to photosynthesize or chemo synthesize), leaving the first level consumers with no food, thus leaving the second level consumers with no food, and so on.
Hope this helped!
Answer:
b
Explanation:
it is a 4 on the scale, I assume that's what you meant by the numbers.
I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.
Breathing, moving blood throughout the body, and so forth.
The products of light-dependent reaction are ATP and NADPH. They are essentially required to fix carbon dioxide and make glucose in light-independent reactions.
Light-dependent reactions are those that use the direct sunlight energy to make usable forms of chemical energy i.e., ATP and NADPH. For this, a pigment called chlorophyll is essential that has the ability to the capture the sunlight.
Light-independent reactions are those that do not directly depend on the sunlight energy to complete their process. Instead they are dependent on the products of light reactions so that they can fix atmospheric carbon dioxide and make glucose for the plant. Calvin cycle is the main process of light-independent reaction.
