100
Why is the bottom trophic level the biggest?
There are more producers and they have the most energy
100
How are humans classified in a food chain or web?
Humans = Consumers
100
What do the first order consumers (primary consumers) have in common?
primary consumers eat producers - herbivores
100
All organisms in an ecosystem get their source of energy from this
All energy comes from the sun
100
The system on Earth that contains the solid land and is subject to plate tectonics
Geosphere
200
How does energy transfer according to the energy pyramid?
Energy Pyramid - energy decreases 90% per level
energy transfers directly from A to B, B to C, and C to D
200
Where are producers on Energy Pyramids, Food Chains, and Food Webs?
Producers - bottom of food web and first organism on Food chains and webs
200
Which feeds on more - the alligator or raccon?
They both feed on 3 separate animals
200
This type of consumer eats primarily meat
Carnivore = Tertiary consumer - eats meat
200
A thin layer on the outside of Earth, accounting for less than 1% of Earth's Volume
Crust
300
Which trophic level (step) on an energy pyramid uses photosynthesis?
Producers (plants) use photosynthesis
300
What do arrows represent on food chains and webs?
Arrows represent direction of energy flow
300
Which animal(s) prey on the sunfish?
Bass , Egret, Turtle feed on sunfish
300
This type of consumer eats both plants and animals
Omnivore = secondary consumer - eats plants & animals
300
The innermost geologic layer of planet Earth; it is primarily a solid ball believed to be composed of an iron-nickel allow with some other elements
Inner Core
400
How much energy would be available to the tertiary consumer?
25 K cal
400
According to this table which food chains are possible?
A) Lettuce --> dog ---> sheep ---> Hawk
B) Lettuce --> Caterpillar ---> Wild Pig ---> Lion
C) Flowers --->Lion ---> Fox ---> Sheep
D) Grass --> Sheep ---> Fox ---> Crocodile
B) Lettuce ---> Caterpillar --->Wild Pig ---> Lion
D) Grass ---> Sheep ---> Fox ---> Crocodile
400
How would mushrooms (decomposers) be incorporated into the food web?
All arrows point to decomposers - they receive energy from everything, but have less energy than producers
400
When plants and animals die, they can be consumed by mushrooms, bacteria, and worms for their energy. What type of organisms are they?
Decomposers = mushrooms, worms, bacteria
400
A layer of silicate rock between the curst and the outer core; it is predominately solid, but on geologic time scales it behaves like a viscous fluid
Mantle
500
What would happen to the energy pyramid if all decomposers disappeared?
Dead plants and animals would pile up and energy would not be recycled
500
A student built and aquatic biome that includes plants, snails, and small fish. He noticed that all the snails were eaten by the fish. Which list best represent energy flow?
A) Sun <--- Plants <--- Snails <---Fish
B) Sun ---> Plants ---> Snails ---> Fish
C) Fish --> Snails ---> Plants ---> Sun
D) Sun <--- Snails <--- Plants <--- Fish
B) Sun ---> Plants ---> Snails ---> Fish
500
Which animal is both a primary and secondary consumer?
fruits/nuts (producer) ---> Bird (primary consumer)
Grass (producer) ---> grasshopper (primary consumer) ---> bird (secondary consumer)
500
Where do decomposers get their energy - and how much energy is available to them?
Decomposers - energy from dead plants and animals. Less than primary producers
500
A fluid layer about 2,260 km thick, composed of mostly iron and nickel, that lies above Earth's solid inner core and below its mantle
Outer Core
