Name 4 inherited traits of leaves
When many organisms have similar needs, what do they do?
Compete for resources
1.A squirrel eats an acorn
2. The grass gets energy from the sun
3. A grasshopper hops on a rock
4. Clouds form in the sky
5. A student chases a butterfly
List all that are an example of a living thing interacting with a non-living thing.
2, 3
What structural adaptation do conifers use to protect their seeds?
Cones (Pinecones)
How can one animal depend on another to survive?
It could be access to food or protection
Squirrels which live in cities make their nests in the treetops. Squirrels are often found near park benches. What learned behavior might lead the squirrels to live near the park?
The squirrels have learned where people drop food.
Which change would most likely occur if all the producers in an ecosystem were removed?
The consumer population would decrease because they would not have food.
A cow eating grass is an example of..
A living thing interacting with another living thing
Turtles and snails both have strong shells on their backs. How does this adaptation most likely help them?
It protects them from predators.
Describe the flow of energy in a food web.
Starts with the sun and then producers (who use the sun's energy to make their own food). Then to consumers (who eat producers or other consumers) then to decomposers (who break down dead organisms).
Crayfish offspring look like their parents by having similar body parts. Would this be a learned behavior or an inherited trait?
Why do animals change their environment to meet their needs?
Animals need food, water, shelter, and space so they change it to make sure they can survive.
Give an example of two living things interacting.
The size and shape of a bird's beak are related to the type of food that the bird eats. Describe the beak of a bird that drinks nectar from deep inside a flower.
Long and narrow
Wild celery > Grasshoppers > Civets > Leopards.
Which organism eats only consumers?
Leopards
The caterpillars of monarch butterflies eat milkweed leaves. Milkweed leaves contain ssap that is toxic to many animals, but not to monarch butterfly caterpillars. This sap makes the monarch butterfly caterpillars toxic to predators and protects them from being eaten.
Which of these is an inherited trait of monarch butterfly caterpillars?
A The size of the milkweed leaves the caterpillars eat.
B The ability of the caterpillars to eat toxic leaves without being harmed.
C The number of milkweed leaves the caterpillars eat each day.
D The number of leaves on the milkweed plants.
B
Kudzu is a fast-growing Asian vine that was introduced into the United States. Kudzu quickly uses available resources and can completely cover the plants in an area. What effect does the rapid growth of kudzu most likely have on an ecosystem?
A The number of other plants increases
B The water supply in the area increases
C Weather patterns in the area change
D The variety of native plants decreases
D
Which of these is not an example of a living thing interacting with another living thing?
A. A horse has bacteria in its mouth
B. A raccoon digs in a trashcan
C. A bird sits on a tree branch
D. A child pokes a worm in the dirt
B
