What is an omnivore?
An organism that eats both plants and animals
100
What is the secondary consumer in the food chain below?
The small fish

Plants and animals
100
Identify the Producer.
number 1

What is a detritivore? And give an example.
A detritivore is an organism that eats the dead organisms.
Ex: Mushroom, bacteria, vultures
200
What are ALL the primary consumers in the food web?
Grasshopper
butterfly
fruit fly
200
Does the primary consumer directly or indirectly give energy to the tertiary consumer?
Indirectly
200
Without nitrogen and the nitrogen cycle, what would happen to the plants?
They would be yellow in color, they would grow poorly, and produce small fruits and flowers.
200
What letter represents the fourth trophic level?
B
300
What is the difference between a consumer and a producer?
Consumer- is an organism that eats other organisms for energy
Producers- organisms that make their own food
300
What is the difference between a food chain and a food web?
Food chain shows one flow of energy. Food web shows multiple flows within an ecosystem.
300
What animals are in the third trophic level?
Frog
Spider
Fox

In the matter cycle arrows go in a circle. In a food web they point in one direction. Why?
Matter is always being cycled back
- moves continuously
Food chain is one flow and eventually ends
- one direction
300
What type of organism would be found at the D level? (consumer level)
Primary consumer

What is nitrogen fixation?
The process by which nitrogen gas from the atmosphere is converted into a form plants can use
400
The frog is considered what type of consumer? Is it herbivore, omnivore, or carnivore according to this food chain.
Secondary consumer, carnivore
400
How many Joules would be found at the question mark section? And what type of consumer would this be?
62, secondary consumer

Which statement describes the importance of the water cycle?
A. Water is cycled through the biosphere which is important for sustaining life in different ecosystems.
B. Water leaves clouds in the form of precipitation and stays in lakes and oceans indefinitely.
C. Water evaporates and turns into precipitation.
D. Water transpires from different plants and condenses into clouds. Clouds then move around the globe, circulating water, which is important for many physical processes.
A. Water is cycled through the biosphere which is important for sustaining life in different ecosystems.

What is transpiration?
process by which plants release water vapor into the atmosphere through their leaves

How much energy is lost from one energy level to the next? What form is it lost in?
90% is lost in the form of heat
500
Correctly label the parts of the water cycle and quickly describe each one.
1. Condensation- forms clouds
2. Precipitation- rain/ water
3. Transpiration- plants release water vapor through leaves
4. Evaporation- water turned into a gas

Identify the consumer levels of of each organism.
Producer- grass, primary consumer- grasshopper, secondary consumer- frog, tertiary consumer- snake
