An organism that eats only meat.
What is a carnivore?

A model that shows how much energy flows through a food web, with producers having the most energy and high level consumers having the least energy.

What is a food/energy pyramid?

100

In the water cycle, when liquid water turns into a gas in the atmosphere, this is called?

Evaporation

100
Why are decomposers important organisms in a food web? A) They produce oxygen. B) They prey on carnivores. C) They are food for producers D) They return nutrients to the soil
What is they return nutrients to the soil?
100

Most of the freshwater on Earth is found where?

Ice caps & Glaciers

200
An organism that makes its own food.
What is a producer?

Consider this food chain: grass => grasshopper => mouse => snake. Which organism is an herbivore?

What is the grasshopper?

200

What is the one process that naturally removes Carbon gas from the atmosphere?

What is Photosynthesis?

200
Consider the food chain: grass=> grasshopper=> frog=> snake What would happen in the ecosystem if the grasshopper population died? A) snakes would eat the grasshopper B) it would be fine, frogs prefer other insects anyway C) it would be fine, the grass population would increase D) the frog population would die from the decrease in their food supply
What is D, the frog population would die from the decrease in their food supply?

Explain the process of Biomagnification:

The level of toxins/pollutants inside an organisms body increases dramatically as you move up through the food chain. This is because larger animals must eat more than smaller animals, thus, larger predators will have higher levels of toxins in their bodies. 

300
An organism that eats only plants.
What is an herbivore?
300

Consider this food chain: blackberries=> bird => badger => coyote.  To which trophic level does the coyote belong?

Tertiary consumer

Which of the following cycles is not a "TRUE" cycle because some material sinks to the ocean bottom?

PHOSPHORUS

300
Which is true regarding an energy pyramid? A) carnivores occupy a larger level than herbivores B) herbivores occupy a smaller level than producers C) consumers occupy the level below producers D) producers and carnivores occupy the same level
What is B, herbivores occupy a smaller level than producers?
300

If they find their way into aquatic environments, which two main nutrients can cause Eutrophication?

Nitrogen & Phosphorus

400
An organism that eats both plants and animals.
What is an omnivore?
400

When a frog eats a grasshopper, how much of the grasshopper's energy is transferred to the frog? A) 10% B) 25% C) 50% D) 90%

A. 10%

400

The process by which bacteria convert Nitrogen gas into Nitrate is called?

Nitrification

400

Which of the following organism is a secondary consumer in the food chain? A). Wheat B). Mouse C). Fox D). Wolf

C. Fox

A diagram that shows the flow of energy from one organism to another.
What is a food chain?

In a Mississippi swamp, Fish eat algae, blue herons eat fish, and alligators eat blue herons. If the algae originally has 4250 kcal of energy, how much energy will the alligator receive?

4.25 kcal

The White Cliffs of Dover in the UK are made almost entirely of Limestone. Limestone is a reservoir for which chemical cycle?

CARBON

BONUS! -- Name the chemical that is produced when water reacts with Carbon Dioxide. This is causing the oceans to become more acidic!

500

Explain why the amount of energy dramatically decreases as you move up the food chain to high-level consumers:

Most of the energy at each level is lost to the environment as heat, and cannot be regained. Therefore, each level of consumer receives less and less.

500

Name the chemicals that associated with plastic pollution, and are common in the Biomagnification process:

PCB compounds
