Adaptations
Why does an oak tree have leaves and a cactus does not?
Oak trees lose excess water through transpiration. A cactus does not have excess water and needs to conserve its water, so it has spines.
Lions hunting and stalking near water sources for prey that are taking a drink is an example of _________.
a learned behavior
Describe the nymph stage.
The intermediate stage. Organisms look like miniature versions of adults. They molt over and over again as they grow.
True or False: A bird using mud to create a nest is an example of a living thing interacting with a nonliving thing.
True. Birds are living and mud is nonliving.
The sun rises in the _____ and sets in the _____.
The sun rises in the EAST and sets in the WEST.
Name two adaptations that allow predatory birds to catch and eat their prey.
Talons and sharp, curved beaks
Name an example of an inherited trait a squirrel has as well as a learned behavior.
Inherited-brown fur, bushy tail, big eyes, etc.
Learned-stealing food from a bird feeder, going to park benches for food, etc.
Describe the nymph stage.
The intermediate stage. Organisms look like miniature versions of adults. They molt over and over again as they grow.
How would cutting down a forest affect the Carbon Dioxide-Oxygen Cycle?
What is the difference between reflection and refraction?
Reflection is the bouncing of light and refraction is the bending of light.
How are bright colored petals an adaptation that benefits flowers?
The bright colors attract insects to the flowers and allows pollination to occur.
Scientists have created fruit hybrids such as the Tangelo and Plumcot by interbreeding two different types of fruit together. The Plumcot has traits of both the Apricot and Plum. Are these traits aquired or inherited?
Inherited
Describe the larva stage.
The organism looks completely different from the adult stage. The organism eats and grows before it transforms.
A Cattle Egret picks parasites off of livestock and eats them. What kind of symbiotic relationship is this?
Mutualism-they both benefit
Describe how fossil fuels are formed.
Organic matter (dead plants and some dead animals) died in large amounts and were buried quickly. Over millions of years, with heat and pressure, the carbon in the organic matter became fossil fuels.
Name 3 adaptations a cactus has to take in and/or conserve water and how they benefit a cactus.
Waxy stem-conserves water by preventing transpiration
Spines-protect cactus from predators, prevent transpiration
Shallow root system-takes in water quickly after it rains
Are insects molting an example of a learned behavior or inherited behavior?
Inherited behavior- they do not have to practice or learn to do this. It occurs naturally because their body has outgrown its outer covering.
Describe the pupa stage.
The stage where an organism seems to be at rest while it is transforming from larva to adult.
_______ transfers the most energy in a food web.
Producers
How is a U-shaped valley formed?
How is a canyon formed?
How is a delta formed?
U shaped valley-ice erosion (glacier)
Canyon-water erosion (river)
Delta- water depositing sediment where a river meets an ocean
A plant called "Devil's Claw" has seeds with two hooks on the end. They easily get snagged in animals' fur. How is this an adaptation that benefits the plant?
The animals can transport the seeds and spread them.
Mockingbirds get their name by "mocking" or mimicking other birds or noises. Is a Mockingbird mimicking a car alarm a learned or inherited behavior? Why?
Learned because though they are born with an instinct to make noise, they must hear the car alarm and then learn to mimic it.
What are the similarities and differences between incomplete metamorphosis and complete metamorphosis?
They both have eggs and adults.
Incomplete has nymphs and Complete has larva and pupa.
Explain the difference between consumer, decomposer, and producer.
Consumer eats other organisms for energy; decomposer breaks down organisms for energy; producer creates its own energy through photosynthesis using the sun's energy.
Biofuels- energy created from burning once living things (ethanol from corn, burning trash)
Wind Energy- wind turbines use wind to turn turbines
Geothermal Energy- heat from below the Earth's surface heats water to create steam and turns turbines
Solar Energy- solar panels capture sun's energy
Hydroelectric- dams open and water rushes in to turn turbines
