In an ecosystem energy flow, the first trophic level is occupied by producers. As energy moves up the trophic levels, what usually happens to the amount of available energy? A. It remains the same B. It increases gradually C. It decreases gradually D. It first increases then decreases ...
In the energy flow of an ecosystem, which of the following statements is correct? A. Energy can be recycled within the ecosystem B. Energy is transferred from consumers to producers C. Energy is lost as it moves through the trophic levels D. All E. nergy is stored in the top - level ...
Ecosystem Energy Flow What is an Ecosystem? An ecosystem includes all the organisms and the nonliving environment found in a particular place.The scale of ecosystems can change based on your perspective. For example you may choose to study your back yard, Chattahoochee National Forest, Lake Lanier...

Energy is what drives the ecosystem to thrive. While all matter is conserved in an ecosystem, energy flows through an ecosystem, meaning it is not conserved. It's this energy flow that comes from the sun and then from organism to organism that is the bas

生产者通过光合作用等方式将太阳能转化为化学能,然后沿着食物链传递给消费者,消费者被分解者分解后,能量释放到环境中。消费者不能自己制造能量,需要从生产者获取;分解者是分解有机物释放能量,不是能量流动的起始;肉食动物是消费者的一部分,也不是能量流动的开始。
A. From the bottom - dwelling organisms B. From the sunlight hitting the water C. From the large fish D. From the water itself 相关知识点: 试题来源: 解析 B。解析:在水生生态系统中,能量流主要从阳光照射到水面开始,因为水生植物(如藻类等)通过光合作用将光能转化为化学能。A选项,底栖生物不是能...
试题来源: 解析 B。解析:本题考查生态系统中的能量流动顺序。在生态系统中,能量首先由生产者通过光合作用等方式固定,然后传递给消费者,消费者死后遗体等被分解者分解,能量流向分解者,所以正确的顺序是Producers → Consumers → Decomposers,选项A、C、D顺序错误。
