What is..Wheat->Mouse->Snake->Owl
A bee eats nectar from a flower, and then is eaten by a bird. Draw a trophic level pyramid to show how the energy flows.
What is..Flower->Bee->Bird
An organism that eats only plants
What is..herbivore
An organism in a food chain that gets energy by eating the producers
what is..primary consumer
Explain what happens to the energy as it moves from producer to the tertiary consumer.
What is..As energy moves from the producer → primary consumer → secondary consumer → tertiary consumer, the amount of energy decreases at each level.

a. Egret provides water for the crab
b. Crab provides energy for the Egret
c. The snail produces it's on food through photosynthesis
d. The cordgrass breaks down other living organisms
What is..The Blue Crab provides energy for the Egret

Where does the energy originally come from?
What is.. the sun

If disease carried by a nonnative species causes a decrease in the giraffe population, how will the energy flow in the ecosystem be affected?
What is..Less food and energy will be available for the lion
Describe 2 ways humans can negatively impact watershed.
What is..Increasing the amount of fuel cars, Industrial waste poured from a factory drain, Fertilizer runoff from farming and agriculture, Deforestation,
A sequence in which energy is transferred from one organism to the next as each organism eats another
what is.. food chain
An organism in a food chain that eats the secondary consumers
what is..tertiary consumer
What happens to the energy not passed to the next organism?
What is..Energy not passed to the next organism is primarily lost to the environment as metabolic heat

Which level of the energy pyramid would have the least amount of energy?
What is..Level T
Describe 2 ways humans can positively affect watersheds
What is..Planting plants near water systems, Reduce, reuse and recycle household waste, Reducing pollution, Protecting wetlands, Responsible farming/fertilizing
The hierarchical feeding categories of organisms in a food chain
what is.. trophic levels
An organism that breaks down dead plants/animals that can also be at the bottom of the pyramid.
As a result of what happens to the energy, explain what the tertiary consumer must do to survive.
What is..Since less energy is available at the top, the tertiary consumer has to hunt more or consume more prey to meet its energy needs.

What is..100 kilocalories
Describe what would happen if snakes were removed from an ecosystem.
Be as specific and descriptive as you can for all the points!
If all the snakes are removed, the animals they eat (like frogs or mice) would increase because nothing is controlling their population. This could cause those animals to eat too much of their food, like insects or plants, which would throw off the balance of the ecosystem. Also, predators that eat snakes, like hawks, might lose a food source and decrease in number. Removing one organism can affect the whole food web
