Photosynthesis and Primary Production


Photosynthesis according to Zuchora-Walske (2014) is a process by which green plants synthesize there food in the presence of sunlight and chlorophyll by taking in Carbon Dioxide from the atmosphere and water from the soil and releasing oxygen as a by-product.The photosynthetic product is glucose which is used by cells to produce energy or polymerized into starch for storage.

Ponds have variety of plants growing in them that provide food, oxygen and even shelter for animals living around. Plants need sunlight for photosynthesis, therefore plants in ponds exposed to sun photosynthesize more than those situated in shady areas. The food chain in the pond starts with microscopic phytoplankton and algae (Beer & Beardall, 2014).

Bank side areas of the pond are the favorite places for the plants to thrive. These plants include willow herb and meadowsweet. Similarly, the marsh zone found at the water‘s edge also has plants such as Yellow flag iris and sedges (Beer & Beardall, 2014).

According to Beer & Beardall (2014), Aquatic Plants like water lilies have roots that are buried in the mud along the pond bed and the leaves and flowers float on the surface. Photosynthesis in aquatic plants occurs the same way as the terrestrial plants. Water plants has their roots in the pond water to absorb water, exposed leaves to ease absorption of Carbon (IV) oxide and sunlight.

Beer & Beardall (2014) indicated that the submerged plants thrive and adapted to grow under low light so, they obtain Carbon (IV) oxide from water during respiration by fish and other water animals. The rate of photosynthesis in these plants is slow because of the dim radiation.
