Nitrogen must be converted into nitrates before organisms can use it. If soil lacks nitrogen fixing bacteria, then it has few nitrates for the plants to take in.

Do stomata close when there is a lack of water in soil or a lack of carbon dioxide in the atmosphere?
Arte-miy333 [17]

<em>When water is abundant:</em>

-Temporal regulation of stomata is used:

Open during the day

Closed at night

- At night, there is no photosynthesis, so no demand for CO2 inside the leaf.

- Sunny day = demand for CO2 in leaf is high = stomata wide open.

- As there is plenty of water, plant trades water loss for photosynthesis products.

-  If the leaf's CO2 concentration is low, the stomata will stay open to continue fueling photosynthesis.

- High temperatures will also signal stomata to close.

- When limited water is available in the soil, plants try to prevent water loss.

How do changes in nutrient affect biodivesity
lord [1]
Climate effects and human impacts, that is, nutrient enrichment, simultaneously drive spatial biodiversity patterns. However, there is little consensus about their independent effects on biodiversity. ... Species turnover rates caused by nutrients do not increase toward higher temperatures

Which of the following is necessary for the light-independent reactions to proceed?
Yanka [14]

Answer;

C) ATP

Explanation;

-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions).

-The two products of the light-dependent reactions of photosystem are ATP and NADPH.  The movement of high energy electrons releases the free energy that is needed to produce these molecules.  The ATP and NADPH are used in the light-independent reactions to make sugar.

-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
