|
Energy flow
|
The flow of energy from 1 species into another
PICTURE - zebra eating grass to get energy |
|
|
Producer
|
A plant
Trophic level = 1 Anything that can photosynthesize - grass, tree, cyanobacteria |
|
|
Consumer
|
Any animal
Anything that can't photosynthesize PICTURE - the lion eats the buffalo to get energy |
|
|
Primary consumer
|
Eats plants - normally grass
Trophic level = 2 PICTURE - the rabbit eats grass to get energy |
|
|
Secondary consumer
|
Eats animals
Trophic level 3 PICTURE - the lion eats the buffalo to get energy |
|
|
Tertiary consumer
|
Trophic level 4 - a meat eater
PICTURE - The fox is the tertiary consumer |
|
|
Decomposer
|
Eats dead things and breaks them down into nutrients
PICTURE - fungi eating a dead tree |
|
|
Decomposition
|
Breaking down dead plants and animals into nutrients
AB -> A + B |
|
|
Biodegradation
|
Using bacteria to help dead plants and animals decompose
|
|
|
Food chain
|
Shows one feeding relationship - what eats what
|
|
|
Food web
|
Shows many food chains and how they are all connected.
One animal will eat more than one type of food |
|
|
Trophic level
|
Each step in the food chain is 1 trophic level
Producer = trophic level 1 Primary consumer = trophic level 2 Secondary consumer = trophic level 3 Tertiary consumer = trophic level 4 |
|
|
Herbivore
|
Plant eaters - normally eat grass
PICTURE - the rabbit eats grass for energy |
|
|
Carnivore
|
Meat eaters
PICTURE - the lion eats the buffalo for energy |
|
|
Omnivore
|
Eats both plants and meat
PICTURE - the bear eats berries and fish |
|
|
Food pyramid
|
Shows the feeding relationship, loss of energy, and number of organisms at each trophic level
The perch eat the bleak which eat the shrimp |
|
|
Ecological pyramids
|
Show the pyramids of biomass, numbers, and energy
|
|
|
Pyramid of biomass
|
The mass of all the shrimp in the ocean is more than the mass of all the bleak in the ocean
|
|
|
Pyramids of numbers
|
There are more shrimp than bleak
|
|
|
Pyramid of Energy
|
Energy drops 10% moving from one trophic level to the next
It takes 10000 shrimp to support 1000 bleak. |
|
|
Top consumer
|
Top of the food chain
PICTURE - the hawk is the top consumer |
