Energy | Food Chain | Food Webs | Ecosystem | Other |
---|---|---|---|---|
The Sun
What is the source of all energy?
|
The flow and direction of energy
What do the arrows in a food chain represent?
|
False
Why?
True or False: Food webs contain one food chain.
|
All of the biotic and abiotic parts interacting in an environment
What is an ecosystem?
|
Glucose from CO2 and H2O
What do plants produce through photosynthesis?
|
Producers
What are organisms that make their own energy called?
|
Producer
What always begins a food chain?
|
The invasive species will out compete the other predators. Will destroy the ecosystem by eating all the prey. No natural predators
If an invasive species is introduced to a food web how will that affect that ecosystem?
|
Forest
Ocean Desert
Give an example of an ecosystem
|
The sea gull population would go down and the sea star population would increase
kelp---> sea stars---> crabs ---> sea gulls
What would happen if there was a decrease in crabs according to this food chain? |
Primary consumer: insect
Secondary consumer: frog Decomposer: bacteria
Name the primary consumer, secondary consumer, and decomposer: grass ---> insect ---> frog---> bird--> bacteria
|
Cactus, mouse, snake, hawk
Correctly show the flow of energy using these: cactus, snake, mouse, hawk
|
Food chain: one way for energy to flow, simple
Food web: multiple ways for energy to flow, made up of food chains, shows relationships, complex
How is a food web different from a food chain?
|
Habitat: where an organism lives
Niche: an organisms job in its habitat
What is the difference between a habitat and a niche?
|
Yes
Can an abiotic factor affect a biotic factor? Give an example
|
10%
How much energy is transferred from level to level?
|
Vulture
Which of these organisms would be at the top of the energy pyramid: rabbit, wild flower, snake, vulture
|
Nutrients would not be recycled back into the soil.
What would happen if there were no decomposers in an ecosystem?
|
Many ecosystems
What does a biome contain/ is made of?
|
Scavengers get food/energy by eating dead animals, and decomposers get food/energy by breaking down the remains of other organisms. They also live on or near dead things.
How are scavengers and decomposers differ?
|
Root and Stem
What are the two parts of the plant that store the plants energy?
|
The energy decreases.
What happens to the energy the further up it gets in the food chain?
|
It is given off as heat when the organisms breathes, hops, eats
What happens to the energy that is not transferred as energy goes up the energy pyramid?
|
species, population, community, ecosystem, biome
List these from smallest to biggest: population, species. community, biome, ecosystem
|
False
Why?
True or False: these are all biotic-
fox, zooplankton, lion, virus, fungi |
