What are the products of light-dependent reactions? Why are they important in light-independent reactions?

tamaranim1 [39]

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.

If you uncovered fossils of tropical fish and palm trees, what could you say about the environment at the time the fossils forme

Ber [7]

The uncovered fossils of fish and palm trees shows that Earth’s environment has changed. Due to climate change, animals and trees have adapt to it over time. Researchers have found that tropical fish species are likely to leave their homes and populate in cooler waters as the world heats.
