from the air
from the remains of organisms
from the organisms it eats
from the sun
Jose observed a puddle in a schoolyard. He gathered a sample of the water in the puddle and used a microscope to study the organisms that live in this micro-habitat. The table shows his results. What is true of the organisms in this puddle?
They are all the same shape.
They are all mammals.
They are all the same color
They are all small.
A student is studying interactions between organisms in a food web. She wonders what could happen in a prairie ecosystem if foxes suddenly disappeared. Which of the following is the best answer to her question?
If foxes disappear, all other populations will grow.
If foxes disappear, the population of an organism on which foxes fed will likely grow.
If foxes disappear, the population of an organism that feeds on foxes will likely grow.
If foxes disappear, all other populations will shrink.

What is one way that cooperation helps lions to survive?
They live in prides of five to ten adult females and their young, and one or two adult males.
They hunt on their own and then share the food after
They all have a tan color that helps them blend into their environment.
They hunt in a group to increase their likelihood of catching prey.
What form of energy is stored in food?
mechanical energy
chemical energy
kinetic energy
light energy
All cells need energy to carry out life activities. The equation below shows one of the processes cells perform to obtain chemical energy. What process is shown and why do cells perform this process?
This process is photosynthesis, which creates the water that cells need to create oxygen
This process is photosynthesis, which creates the ATP that absorbs radiant energy from the sun.
This process is cellular respiration, which creates ATP, which is a molecule that supplies energy to fuel cell activities.
This process is cellular respiration, which creates the carbon dioxide cells need to generate energy to fuel cell activities.
Green plants use energy from the sun to produce food during the process of photosynthesis. This food provides energy to an entire food chain. What starting materials do the plants use to make this food?
water, phosphorus, and nitrogen
carbon dioxide and water
water and oxygen
soil and water
What is the food that plants produce during photosynthesis?
carbon dioxide
chloroplasts
chlorophyll
glucose
What do animals do with the carbon dioxide produced in their cells during cellular respiration?
combine it with water to make sugar
exhale it in the breathing process
reuse it during photosynthesis
store it for later use
Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is true?
Carbon dioxide is one product of photosynthesis.
Chlorophyll is one product of photosynthesis.
Oxygen is one product of photosynthesis.
Water is one product of photosynthesis.
Which of the following consumers is a herbivore?
vulture
human
horse
cat
Where does the majority of evaporation on Earth occur?
between Earth’s surface and underground aquifers
between the ground and the atmosphere
between the oceans and the atmosphere
between rivers and oceans
A scientist is studying a substance that is cycled through ecosystems. Which of the following substances might the scientist be studying
nitrogen
glucose
copper

Which phrase best describes a consumer in a food web?
an organism that converts light energy into chemical energy
an organism that gets its energy by eating plants or animals
an organism that gets its energy from the sun
an organism that forms the base of the food chain

fox
hawk
rabbit
coyote
What might happen if the rabbit population suddenly shrunk due to disease?
there would be more grass for the deer to eat
there would be more foxes
there would be more hawks
there would be fewer deer
Which of the following is not a reason that wetlands are important ecosystems?
they are a natural flood area
they are home to many mosquitoes and other pests.
they are home to many plants and animals
they filter water and allow it slowly sink down and become groundwater.
If an ecosystem has few trees and lots of grasses, it is probably
a mature ecosystem
not a mature ecosystem
If an ecosystem grows from bare rock and no soil, it is
