Question

Energy flow in an ecosystem, begins with:

• A. Omnivores
• B. Herbivores
• C. Decomposers
• D. Producers

Answer 1

The correct option is D Producers

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. Sun is the source of energy fixed by the primary producers, like plants. Primary consumers, like herbivores, absorb most of the stored energy in the plant through digestion, and transform it into the form of energy they need, such as ATP, through respiration. A part of the energy received by primary consumers is converted to body heat (an effect of respiration), which is radiated away and lost from the system. Secondary consumers, on consuming primary consumers, get the remaining energy from primary consumers.

So, the correct option is D.
