Producing their own food
Eating only plants
Eating only animals
Eating both plants and animals

What would happen to the small fish population if the tadpoles were removed from the food web below?
The small fish population would thrive and grow due to increased food supply
The water beetle population would grow.
The small fish population would loose their food source and the population would drop.
The algae in the ecosystem would grow and thrive
Put the following food chain in the correct order:
seal, seaweed, polar bear, sun, arctic fox
Arctic fox (Scavenger), Sun (energy source), Seaweed (Producer), Polar Bear (Predator), Seal (prey)
Sun (energy source), Seaweed (producer), Seal (prey), Polar Bear (predator), Arctic Fox (scavenger)

What is the function/purpose of a seed?
contain food which supplies energy and materials for growth until the plant grows its first leaves above the ground.
to be circular/round shaped
to provide photosynthesis
provide a home for the plant
What is the function/purpose of the flower?
to look pretty
seeds develop in the part of a flower
to sprout a bud and grow
this usually becomes what we call the fruit
What is the function/purpose of the leaf?
food is made by photosynthesis
leaves take in carbon dioxide from the air, water from the soil, and energy from the sunlight
during photosynthesis, the leaves use light energy to change carbon dioxide and water into food (sugar)
none of the above
What is the function/purpose of the stem?
support the upper parts of the plant
water and dissolved nutrients from the soil travel up the stem in a system of tubes
food from the leaves travel down the stems to the roots
stems also store food for the plant
What is the function/purpose of the root?
anchor plants in the soil
water and minerals are taken from the soil through the roots
many plants such as carrots, store food in their roots
all of the above
Do all plants need the same amount of sunlight, water, and nutrients in the soil?
yes
all plants are the exact same in each ecosystem
no, each plant is adapted to live in its ecosystem
How do seeds mainly travel?
animal fur
wind
sunlight
water
What is a pro for seeds being able to travel?
the air is full of seeds
plants can continue to grow
you will have to brush your dogs fur because it will have seeds in it
all of the above
What is a con for seeds being able to travel?
plants might grow where they are not wanted
plants can continue to grow
we are likely to never run out of plants to provide oxygen
none of the above
How would a plant population possibly decrease?
drought
human
overgrazing
climate change
If you cut into a tree truck, what do the rings inside tell us?
the age of the tree
how much sunlight the tree received
if birds like to live on that type of tree
the rainfall per year (based on three growth)
What adaptation do cactus' have to live in their ecosystem?
reserve water
large root system
pokiness of thorns
Jobs of cactus' niches:
food
water
shelter for some desert animals
all of the above
What are some adaptations you may see in an animal found in an arctic tundra? (click all that apply)
White fur for camouflage
Thick fur
Large ears to release heat
Thick layer of blubber to keep warm
Hibernation during winter
Dessert plants mostly compete for
Sunlight
water
carbon dioxide
space
Which fossil discovery indicates a change in the environment where it was found?
Seashell impressions found in coastal rocks
Snake bones found in the dessert
Shark teeth found in west Texas
Elephant Bones found in the African Savannah
