wunder beta🕸️ Food Chains and Food Webs
Follow the flow of energy from the Sun through producers, consumers, and decomposers, and see how food chains link into tangled food webs.
What you’ll learn
- The Flow of EnergyUnderstand how energy flows from producers to consumers and identify herbivores, carnivores, and omnivores.Energy flows from the Sun into producers, which make their own food, and then into consumers that eat other living things. Consumers are herbivores, carnivores, or omnivores. A food chain traces one path of this energy, with arrows pointing from food to feeder.
- Food WebsUnderstand that linked food chains form a food web showing all the feeding links in a habitat.Because most animals eat several foods and most foods have several eaters, food chains connect into a food web. A meadow web links grass, rabbits, grasshoppers, foxes, and hawks, and tracing or removing an organism shows how the links depend on one another.
- Recyclers and BalanceLearn the role of decomposers, why energy shrinks up the pyramid, and how losing a species ripples through a web.Decomposers like fungi and worms recycle dead material into rich soil so producers can grow again. Energy shrinks at each step up a food chain, so an energy pyramid has many producers and few top predators. Because every link depends on the rest, losing one species ripples through the whole web.
Questions this course answers
Why are green plants called producers?
Producers make their own food using sunlight through photosynthesis, forming the base of food chains.
An animal that eats only plants is called a...
A herbivore is a consumer that eats only plants, like a zebra or a rabbit.
In a food chain diagram, which way do the arrows point?
Arrows point from the food to whoever eats it, following the direction that energy flows.
What is a food web?
A food web is many food chains connected together, showing all the feeding links in a habitat.
What important job do decomposers do?
Decomposers break down dead plants and animals into rich soil, returning nutrients to the ground.
Why are there fewer top predators than producers in an energy pyramid?
At each step up the chain, most energy is used for living and moving, so less passes on, leaving room for fewer predators.
