Term for a nonliving thing
Abiotic

What is photosynthesis?
the process plants undergo when turning sunlight into food/energy (sugar/glucose).
100
What is the neutral pH number?
7
100
Name 1 living thing and 1 nonliving thing
Example: humans, rocks
100
Give an example of a pollinator.
Bees, people, insects.
200
Name 1 factor that affects population size and how it affects population size.
Example: Rainfall
If it rains a lot then the grass grows and thrives, giving a population more energy to sustain themselves.
If there is a drought (no rain), no grass will grow and there would be less energy for a population to sustain themselves.
200
Which of the following is a type of cycle?
A: Water
B: Phosphorus
C: Nitrogen
D: All of the above
D: All of the above

Fill in the blank:
When the atmospheric levels of carbon dioxide increase, the carbon dioxide levels in the ocean____.
Increase

What is an organism?
An individual animal, plant, or single-celled life form.
200
What is the most important pollinator? And why?
Bees, are efficient pollinators and pollinate a majority of the food diversity we have available.
300
What is discrete data?
data that can be categorized into groups
300
Name an example of a
-Producer
-Consumer
-Decomposer
Producer: grass, algae, fruit
Consumer: animals, humans
Decomposer: fungus, worms
300
What numbers are acidic? What numbers are basic?
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
acidic: 0-6
basic: 8-14
300
Give an example of an interaction
interaction between bees and flowers:
bees use pollen to make honey while seeking pollen, they pollinate the flowers.
300
Give an example of a keystones species
Example: a starfish, bees, otters
400
Define carrying capacity in your own words.
The limit an ecosystem can support to sustain everybody.
400
What is an apex consumer?
A predator at the top of the food chain
400
What does the pH scale do?
Tells you how acidic or basic something is.
400
What is a carnivore, herbivore and an omivore?
carnivore: meat-eater
herbivore: plant-eater
omnivore: eats both meats and plant to sustain themselves
400
What is a keystone species?
a species that is necessary to maintain ecosystem health. Without this keystone species the system will become unbalanced.
500
What is this graph telling us and what prediction can you make about the prey/predator populations?
When there are not a lot of predators, the prey population is high. When there are a lot of predators, the prey population is low because they are being eaten.
Over time the prey and predator populations will reflect one another, they will fluctuate.
500
Make a simple food chain using 1 producer and 2 animals.
Example: Grass ----> rabbits ----> hawks
500
Name an example of a(n):
-Acid
-Base
-Neutral pH
Example:
acid- lemon, stomach acid, battery
base- soap, bleach, blood
neutral- water
500
what is the difference between a food web and a food chain?
Food web: shows the transfer of energy within an entire ecosystem
Food Chain: show the transfer of energy in a linear sequence within a few organisms.

What is a pollinator garden? And give an example of a pollinator-friendly flower.
A garden intended to attract pollinators. Milkweed
