Chains & Webs
A simple diagram showing how energy moves from one organism to another.
Food Chain
The ultimate source of energy for all ecosystems.
The sun
The process plants use to make their own food.
Photosynthesis
These organisms break down dead matter in an ecosystem.
Decomposers
What is the capital of California?
This model shows how multiple food chains are connected in an ecosystem.
Food Web
The type of consumer that eats only plants.
Herbivore
The gas that plants take in for photosynthesis
Carbon Dioxide
An example of a decomposer.
Worms, maggots, etc.
What is the only mammal that can fly?
A bat
The first organism in a food chain, which makes its own food.
Producer
The percentage of energy that moves from one level to the next in a food chain.
10%
The process that animals and plants use to break down food for energy.
Cellular respiration
The molecules that decomposers release back into the environment.
Carbon Dioxide and water
What animal has killed the most humans?
A mosquito
This type of consumer is at the top of the food chain.
Apex Consumer/Predator
This group of consumers eats both plants and animals.
Omnivore
The sugar produced during photosynthesis.
Glucose
True or False: Matter is lost when an organism dies.
False
What is the tallest mountain in the world?
Mt. Everest
Unlike food chains, food webs are more accurate because organisms do this when they eat.
Eat from multiple food chains
The reason there are usually more plants than tertiary consumers in an ecosystem.
Energy decreases at each level of the food chain
The equation for photosynthesis in words.
carbon dioxide + water + sunlight → glucose + oxygen
The reason decomposers are important to an ecosystem.
They recycle nutrients back into the environment
Which continent is the least populated?
Antarctica
