Where all the energy comes from
- Almost all the energy in living things can be traced back to one source: the Sun.
- Following that energy through an ecosystem is the heart of ecology.
所有能量从哪里来
- 活的东西中几乎所有的能量都能追溯到一个来源:太阳。
- 追随那能量穿过一个生态系统是生态学的核心。
The original source of energy for almost all ecosystems is the: · 几乎所有生态系统的原始能量来源是:
Producers capture the Sun's energy. · 生产者捕获太阳的能量。
Producers 生产者 capture the energy
- Producers (green plants) capture light energy by photosynthesis 光合作用.
- They turn it into chemical energy stored in glucose — the food that feeds everything else.
A food chain 食物链: arrows show energy passing from producer to consumers 消费者
生产者捕获能量
- 生产者(producers,绿色植物)通过光合作用捕获光能。
- 它们把它变成储存在葡萄糖中的化学能——养活其他一切的食物。
一条食物链:箭头显示能量从生产者传给消费者
Energy flow through a food chain · 能量流过一条食物链
Energy from the Sun enters living things through plants, then passes along the food chain — losing a lot at each step. · 来自太阳的能量通过植物进入活的东西,然后沿食物链传递——在每一步损失很多。
Producers capture energy by: · 生产者通过以下哪种捕获能量:
Green plants photosynthesise to store energy. · 绿色植物进行光合作用以储存能量。
Green plants that make their own food and start a food chain are called . · 制造自己的食物并开始一条食物链的绿色植物叫做。
Producers are the first link in a food chain. · 生产者是一条食物链中的第一环。
Energy passes on
- Consumers get their energy by eating producers or other consumers.
- Energy flows from the Sun → producers → consumers along a food chain.
A savanna ecosystem: organisms linked by feeding relationships
能量传递下去
- 消费者(consumers)通过吃生产者或其他消费者获得它们的能量。
- 能量沿一条食物链从太阳 → 生产者 → 消费者流动。

Energy is lost between stages of a food chain mainly as: · 能量在一条食物链的阶段之间主要作为以下哪种损失:
Respiration, movement and waste lose energy as heat. · 呼吸作用、运动和废物作为热量损失能量。
Energy flows through an ecosystem and is lost, rather than being recycled. · 能量流过一个生态系统并损失,而不是被回收。
Energy must be resupplied by the Sun; only nutrients cycle. · 能量必须由太阳重新供应;只有营养素循环。
Energy is lost at each step
- At every stage, energy is lost as heat (from respiration), movement and waste.
- So less energy is available the further along the chain you go.
Energy flows; it doesn't cycle. Unlike nutrients (carbon, nitrogen), energy is lost at each step and must be constantly resupplied by the Sun. It is not recycled.
每一步都损失能量
- 在每个阶段,能量作为热量(来自呼吸作用)、运动和废物损失。
- 所以你沿链走得越远,可用的能量越少。
能量流动;它不循环。 不像营养素(碳、氮),能量在每一步损失,必须由太阳不断地重新供应。它不被回收。
You've got it
- nearly all energy comes from the Sun, captured by producers (photosynthesis)
- consumers get energy by eating; energy flows Sun → producers → consumers
- energy is lost at each step (heat, movement, waste) — it flows, it doesn't cycle
你掌握了
- 几乎所有能量都来自太阳,被生产者捕获(光合作用)
- 消费者通过吃获得能量;能量从太阳 → 生产者 → 消费者流动
- 能量在每一步损失(热量、运动、废物)——它流动,不循环
