The correct answer is A. some energy is wasted as heat.
Energy is transferred between organisms through the food in a food chin. Food chain begins with producers. They make food using solar energy. They are eaten by primary consumers which are in turn eaten by secondary consumers and so on. Large amounts of energy are lost from the ecosystem when energy is transferred from one organisms to the next. In biologic systems, large amount of energy is lost as metabolic heat when the organisms are consumed by the next level.
Answer:
The simple equation for lactic acid fermentation is glucose ---glycolysis---> 2 pyruvate ---fermentation--> 2 lactic acid. And the molecule for lactic acid looks like this: Lactic acid, also called lactate. This is the end product of lactic acid fermentation.
The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. By this means, nutrients can be moved from the photosynthetic site (the source) to the place where the sugar is being used (the sink) whether it is up or down the stem of the plant.
I would say the most reasonable answer would be D
Hope this helped!!
