Food Chains and Trophic Pyramid

DO NOW

Name as many things in a food chain as you can

So what’s a food chain?

Thing that eats thing that eats thing
that eats thing that eats thing that

Plant “eats” sunlight
Rabbit eats plant
Wolf eats rabbit

So what’s a trophic pyramid?

Same thing, but in layers. Shows energy transfer.

CARNIVORE
HERBIVORE
PLANT

Reorder

Reorder the following to match a food chain/trophic pyramid from bottom/start to end.

• SUNLIGHT

• Plants

• Herbivores (primary consumers)

• Carnivores (Secondary Consumers)

• Decomposers/Scavengers

Plants. They get energy from the SUN, water, and CO2.

​​Producer

Herbivores. They eat the plants.

Primary Consumer

Carnivores. They eat the herbivores (and other carnivores sometimes

​​Secondary Consumer

​We have fancy words for stuff in the trophic pyramid

Carnivores who eat OTHER carnivores.

Tertiary Consumer

​They eat dead animals.

Scavenger

They break down dead stuff (including plants).

Decomposer

Match

Match the organism to its job in the trophic pyramid.

• Rabbit

• Wolf

• Plant

• Vulture

• Mushroom

Food Chain Project

We will be making a physical food chain to hang from the ceiling.

EVERY one has to make a chain.

​

Food Chains show what eats what, like a trophic pyramid

Woodland
Grassland
Tundra
Swamp

Desert
Rainforest
Coral Reef
Oceanic/Marine

Pick a biome

First Steps

Make yourself a google doc with this information. You need 3 carnivores, 3 herbivores they eat, and 3 plants those herbivores eat.

Google Docs

Look up plants and animals that live in your biome. You need to make a list of what eats what. I would start with carnivores, then work your way down.
