Answer: a. dead organisms from the marine food web.

c. liberation through ATP hydrolysis in living organisms.

Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling.  In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.

Why are most of the stomata on the bottom of the leaf
larisa86 [58]

Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.

During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent  the leaves from taking in too much water during rainfall.

You observe a plant on your windowsill that is growing at an angle toward the outside. This is an example of a living thing ____
katrin2010 [14]

Answer:

response to stimuli / tropism

Explanation:

The plants and animals always respond to stimuli. It is an innate character of all living things. When a bright light falls on the eye, it closes immediately. This is responding to the stimuli. When someone touches the leaves of touch-me-not plants it closes its leaves due to the external stimuli.

The plants respond to the light. Because it does photosynthesis in the presence of light. Therefore, the leaves and branches of the plants always bend towards the light. This process is called phototropism.

Similarly, the roots of the plants move towards gravity under the ground. This is called geotropism.

Besides phototropism and geotropism, other types of stimuli are there - hydrotropism(response to the water), chemotropism(response to certain chemicals).

That's why the plants growing on the windowsill move towards outside where light comes.
