andrew-mc [135]

Answer: It can decrease or increase a population of species.

Explanation: Limiting factors include the availability of food, water, shelter, and etc. When a population of species are limited in any of these, they either move or adapt to their environment. So, population tends to decrease. The population that may finds an abundance of resources will find that their numbers tend to increase. This cycle is repeated over and over again.

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.
