When Algae Undergo Photosynthesis: How Do Concentrations Change?

Aquatic plants and algae play a vital role in ecosystems, mainly through photosynthesis. Algae are often overlooked or misunderstood, but understanding their behavior, such as how concentrations change during photosynthesis, can improve our knowledge of aquatic health.

In simple terms, photosynthesis is a process where light energy is converted into chemical energy. As you read on, you’ll gain fascinating insights into how algae photosynthesis affects concentrations of various substances in the water.

Be prepared to explore the fascinating world of algae, and let’s unravel the mysteries of photosynthesis together!

The Photosynthesis Process in Algae

Understanding Photosynthesis

Photosynthesis is a biological process that converts light energy into chemical energy stored in glucose molecules. This process involves the absorption of light by pigments in algae, which are used to produce glucose and oxygen.

Light-dependent & Light-independent Reactions

The photosynthesis process consists of two main stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle). Light-dependent reactions occur in the chloroplasts, resulting in the production of oxygen and ATP (adenosine triphosphate), an essential energy-carrying molecule. In contrast, light-independent reactions use ATP to convert carbon dioxide (CO2) into glucose, which undergoes various metabolic processes.

Changes in Concentrations During Photosynthesis

Dissolved Oxygen (DO) Increases

During the light-dependent reactions, algae produce oxygen as a byproduct. This oxygen is released into the water, increasing the dissolved oxygen (DO) concentration. High levels of DO are essential for maintaining the health of an aquatic ecosystem as they support the survival of various aquatic organisms.

Decrease in CO2 Concentrations

As the Calvin cycle begins, algae consume CO2 from the water to produce glucose. Since CO2 is being used up, its concentration in the water decreases. A decrease in CO2 concentration can also contribute to a rise in pH levels since CO2 forms carbonic acid when dissolved in water.

Increase in pH levels

The reduction of CO2 in the water can lead to higher pH levels, making the water more alkaline. Photosynthesizing algae consume hydrogen ions (H+), which interact with bicarbonate (HCO3-) to form CO2 again. This reaction buffers the system from pH spikes, so photosynthesis can often regulate the pH in the environment.

Nutrient Uptake Changes

Algae require various nutrients for their growth, such as nitrogen (N) and phosphorus (P). As algae grow, they take up these nutrients from the water, resulting in a decrease in nutrient concentrations.

Dealing with Algae in Aquatic Systems

Algae Elimination Techniques

Having a controlled growth of algae is essential to maintaining balanced aquatic systems. There are various methods to control algae growth, such as mechanical removal, chemical treatment, and introduction of algae-eating organisms.

Can Oscars eat algae eaters?

You might think that adding algae eaters to your aquarium would solve the problem, but you should consider the compatibility of different fish species. Check out this informative article about Oscars and whether they would eat algae eaters to make informed decisions for your aquarium.

Algae Control Products

One popular method to control algae growth is using algae control chemicals. However, these chemicals might harm other aquatic inhabitants. For more information, read this article about whether algae remover can kill fish or not.
