Understanding the Conservation of Mass and Energy in Living Systems

In ecosystems, the Laws of Conservation of Mass and Energy play crucial roles in maintaining balance. The Law of Conservation of Mass states that matter cannot be created or destroyed; it only changes forms. For example, during photosynthesis, plants absorb carbon dioxide from the air and water from the soil, using sunlight and chlorophyll to convert these materials into glucose and oxygen. This process shows how matter is transformed and transferred in the carbon cycle, as carbon moves from the atmosphere into living organisms. Similarly, the Law of Conservation of Energy indicates that energy is also conserved during these processes. Energy from sunlight is captured by plants and converted into chemical energy, which is then passed on to herbivores and higher-level consumers in the food chain. As a result, both mass and energy are continuously cycled through the ecosystem, demonstrating the interconnectedness of living systems.

True False
The Law of Conservation of Mass states that mass cannot be transformed or destroyed, only created.

During photosynthesis, plants convert light energy from the sun into chemical energy in the form of glucose.

In an ecosystem, energy flows from the primary consumers to producers.

The process of cellular respiration in animals transforms chemical energy into ATP.

Consumers are the primary organisms in an ecosystem to capture light energy from the sun.

As energy moves through the food chain it is destroyed.

Here are the answers to the true/false questions based on the provided information:

  1. The Law of Conservation of Mass states that mass cannot be transformed or destroyed, only created.
    False – The Law states that matter cannot be created or destroyed; it only changes forms.

  2. During photosynthesis, plants convert light energy from the sun into chemical energy in the form of glucose.
    True – This is a correct statement about the process of photosynthesis.

  3. In an ecosystem, energy flows from the primary consumers to producers.
    False – Energy flows from producers (plants) to primary consumers (herbivores).

  4. The process of cellular respiration in animals transforms chemical energy into ATP.
    True – Cellular respiration indeed converts chemical energy stored in glucose into ATP.

  5. Consumers are the primary organisms in an ecosystem to capture light energy from the sun.
    False – Producers (such as plants) are the primary organisms that capture light energy.

  6. As energy moves through the food chain it is destroyed.
    False – Energy is not destroyed; it is conserved but converted into different forms and dissipated as heat.
