|
Energy
|
The ability to do work
|
|
|
Photosynthesis
|
Producers pull carbon dioxide and water with sunlight from the atmosphere and release sugars and oxygen.
|
|
|
* Chemosynthesis *
|
Organic compounds made by bacteria using energy from chemical reactions (hydrogen sulfide) in the absence of sun.
|
|
|
Producer
|
An organism that makes it's own food - a plant.
|
|
|
Consumer
|
An organism that needs to eat other organisms for their food.
|
|
|
Primary Consumer
|
An animal that only eats primary producers (herbivore).
|
|
|
Secondary Consumer
|
An animal that either eats only consumers (carnivore) or eats consumers and producers (omnivore).
|
|
|
Tertiary Consumer
|
An animal that eats other carnivores and omnivores.
|
|
|
Herbivore
|
An animal that only eats plants (primary consumer).
|
|
|
Carnivore
|
An animals that eats only other animals (secondary consumer).
|
|
|
Detritivore
|
An animal that breaks down animal, plant, or human waste and returns carbon to the ground.
|
|
|
Scavenger
|
An animal that eats dead animals.
|
|
|
Decomposer
|
Breaks down waste and puts it and the carbon in the ground.
|
|
|
Food Chain
|
A linear display of feeding relationships.
|
|
|
Food Web
|
A diagram of many feeding relationships.
|
|
|
What are the three types of energy?
|
Solar- transferred from sunlight; Chemical- transferred from chemical bonds, can be stored/released by beings; Heat- the "waste" product
|
|
|
What is two ways energy can be transferred?
|
1. from the sun - solar
2. organisms eating each other -> directly and indirectly. |
|
|
What are the four levels of feeding?
|
|| Tertiary Consumers ||
|| Secondary Consumers || || Primary Consumers || || Primary Producers || |
|
|
In a trophic pyramid, how is energy lost as you go up the levels?
|
Each level uses 90% of the carbon energy, and then passes 10% of the left-over energy to the next level.
|
|
|
What does energy turn into when it is lost?
|
Biomass or lost in heat.
|
|
|
How can the energy transfer be interrupted?
|
* loosing natural predators
* organisms with specific food preferences * toxins in the environment |
|
|
Create a food chain.
|
Acorn → squirrel → fox
|
|
|
Create a food map.
|
* more than one organism can
eat another food type * '→' points to eating organism |
|
|
Compare and contrast a food chain and a food web.
|
Compare: both display feeding relationships.
Contrast: F. Chain is one chain, F. Web has many chains. |
