Answer: Ecosystem Services

Explanation: Simply put,Ecosystem services refer to all the benefits that man enjoys from his relationship with the ecosystem.Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provision,regulation and cultural services that directly affect people, and supporting services needed to maintain the other services. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.

We depend on nature for our survival – without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. Studies also show that people who spend time in nature tend to be happier than those that don’t. Being outdoor can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the compromise we are making between nature and industrial development.

Three-carbon molecules of PGA are converted to G3P small sugar molecules by _____, which come from the light reaction.

anyanavicka [17]

<h3>Answer;</h3>

ATP and NADPH

<h3>Explanation;</h3>

Three-carbon molecules of PGA are converted to G3P small sugar molecules by ATP and NADPH, which come from the light reaction.

Photosynthesis, a process in which green plants use energy from the sun to make their own food, involves two types of reactions, light reactions in light stage and light independent reactions in dark stage.

During the light reactions ATP and NADH are generated from the electron transport chains, which are then taken to the second stage (light independent stage) of photosynthesis. During the Light independent stage the energy stored in ATP and NADH is used to convert 3-carbon PGA to G3P.
