Use the picture below to answer the question that follows.

It is a picture of cows eating in a field on the edge of the woods

Explain how the products of photosynthesis, glucose and oxygen, produced by the main plant in the picture benefit both the plant and the consumers that appear in the surrounding environment.

Hint: Consider the importance of the products of photosynthesis.

1 answer

Photosynthesis is the process through which plants, including the main plant in the picture, convert sunlight, carbon dioxide, and water into glucose and oxygen. Both of these products have significant benefits for the plant itself and for consumers in the surrounding environment, such as the cows.

Benefits to the Plant:

  1. Glucose as an Energy Source: The primary product of photosynthesis, glucose, serves as an essential energy source for the plant. It is used in cellular respiration to produce ATP (adenosine triphosphate), which powers various metabolic processes necessary for growth, reproduction, and maintenance.

  2. Growth and Development: Glucose is also a building block for other organic compounds. It can be used to synthesize cellulose, which is crucial for the plant’s structural integrity, as well as other carbohydrates, proteins, and lipids that contribute to the plant's overall health.

  3. Storage: Some of the glucose produced during photosynthesis can be stored as starch, allowing the plant to have energy reserves during periods when photosynthesis is not occurring (e.g., at night or during winter).

Benefits to Consumers (Cows and Other Herbivores):

  1. Food Source: The glucose produced by the plant contributes to the growth of plant tissues (leaves, stems, roots), making it a vital food source for herbivores like cows. These animals consume the plants, breaking down the carbohydrates during digestion to access the energy stored in them.

  2. Oxygen Production: Oxygen, the other key product of photosynthesis, is released into the atmosphere as a byproduct. This oxygen is crucial for all aerobic organisms, including cows, as they rely on it for cellular respiration to convert food into usable energy.

  3. Ecosystem Health: The presence of plants that perform photosynthesis contributes to overall ecosystem health. By providing food and oxygen, they support various species, including herbivores and predators, forming a balanced food web.

In summary, the products of photosynthesis, glucose and oxygen, not only sustain the plant that produces them, allowing for its growth and longevity, but also play an essential role in supporting the survival and health of consumers in the ecosystem, such as the cows pictured in the field.
