Who eats whom
- In any habitat, organisms are linked by what they eat.
- These feeding links form food chains 食物链 and, joined together, food webs 食物网.
谁吃谁
- 在任何栖息地,生物都由它们吃什么连接起来。
- 这些摄食连接形成食物链(food chains),连在一起,形成食物网(food webs)。
Food web energy route · 食物网能量路径
Move energy from producer to consumers and see why each link loses energy. · 将能量从生产者转移到消费者，并观察每一环节为何损失能量。
In a food chain, the arrows show the direction of: · 在食物链中，箭头表示方向的是：
Arrows point from the eaten to the eater. · 箭头指向被吃者到捕食者。
Food chains
- A food chain shows the flow of energy from one organism to the next.
- The arrows point in the direction the energy flows (from the eaten to the eater).
A coral reef: a rich ecosystem where many food chains link into a food web
食物链
- 一条食物链显示能量从一个生物到下一个的流动。
- 箭头指向能量流动的方向(从被吃的到吃的)。
一个珊瑚礁:一个丰富的生态系统,许多食物链在其中连成一个食物网
A food web is: · 食物网是：
Food webs link multiple chains. · 食物网连接了多条食物链。
Food webs
- Most organisms eat more than one thing, so chains link into a food web.
- A food web shows all the feeding relationships in a habitat.
Arrows point from each organism to the one that eats it — the direction energy flows.
食物网
- 大多数生物吃不止一种东西,所以链连成一个食物网。
- 一个食物网显示一个栖息地中所有的摄食关系。
箭头从每个生物指向吃它的那个——能量流动的方向。
A primary consumer is an organism that eats: · 初级消费者是指以______为食的生物：
Primary consumers eat producers. · 初级消费者以生产者为食。
Decomposers break down dead matter and recycle nutrients. · 分解者分解死亡有机物并回收养分。
Bacteria and fungi recycle nutrients back to the soil. · 细菌和真菌将养分循环回土壤。
The first organism in every food chain is a . · 每条食物链的第一个生物是。
Producers capture the Sun's energy. · 生产者捕获太阳能。
Feeding levels
- Producer → primary consumer (herbivore 食草动物) → secondary consumer → and so on.
- Decomposers 分解者 (bacteria, fungi) break down dead matter and recycle nutrients.
The arrow points TO the eater. In a food chain, the arrow shows the direction energy moves — from the food to the consumer. "Grass → rabbit" means the rabbit eats the grass.
A food web is several food chains linked together
摄食层次
- 生产者 → 初级消费者(食草动物)→ 次级消费者 → 以此类推。
- 分解者(decomposers,细菌、真菌)分解死的物质并回收营养素。
箭头指向吃的那个。 在一条食物链中,箭头显示能量移动的方向——从食物到消费者。"草 → 兔子"意味着兔子吃草。
一个食物网是几条食物链连在一起
You've got it
- a food chain shows energy flow; arrows point to the eater
- linked chains form a food web (most organisms eat several things)
- levels: producer → primary → secondary consumer; decomposers recycle nutrients
你掌握了
- 一条食物链显示能量流动;箭头指向吃的那个
- 连接的链形成一个食物网(大多数生物吃几种东西)
- 层次:生产者 → 初级 → 次级消费者;分解者回收营养素
