The illustration shows some of the organisms in an ecosystem.
Which organism is the MOST LIKELY food source for the deer?
mountain lion
plant
hawk
squirrel
A student wants to grow a sunflower plant. He knows it is a producer
and can make its own food.
The plant needs all of the following in order to make its own food EXCEPT
carbon - dioxide
insects
water
sunlight
Which of the following is NOT needed for a producer to make its own food?
Oxygen
Carbon dioxide
Water
Sunlight
These two species of birds, the egret and heron, eat the same types
of fish as their maindiet. They live in the same ecosystem.
How would the egrets in this area MOST LIKELY respond if all of the herons were removed from the area?
They would move to different ponds.
They would change to another diet.
They would build fewer nests.
They would have an increase in population.
What do producers need to make their own food?
Heat, carbon dioxide, and water
Sunlight, oxygen, and water
Heat, carbon dioxide, and oxygen
Sunlight, carbon dioxide, and water
In 2011, fires in Bastrop County, Texas, were the most destructive
wildfires in Texas history.
The fire spread through the Loblolly pine trees and scorched
nearly 5,700 acresof Bastrop State Park.
The majority of the Houston Toad’s habitat was lost, and
the Lost Pines Forest was heavily affected.
A food web of the Bastrop State Park environment is shown below.
The loss of habitat for the Houston Toad most likely affected
the food web by -
causing a decrease in the number
of wildflowers
causing an increase in the number
of insects
causing a decrease in the number
of armadillos
causing an increase in the number
of opossums
Sandra plants a vegetable garden in her backyard. She plants yellow squash and red peppers. Unfortunately, slugs begin eating the vegetables while squash bugs begin drinking the sap from the squash vines. The slugs and the squash bugs are both
plants
consumers
decomposers
producers
Look at the food web of a pond ecosystem.
Which food chain shows the correct flow of energy in the pond
of the food web?
Which of the following statements describes how consumers get food?
Consumers are able to make
their own food.
Consumers must get food
from other organisms.
Consumers make food or get food
from other organisms.
Consumers use sunlight and
carbon dioxide for food.
The diagram shows a grassland food web.
The grassland ecosystem is experiencing a drought where very little
rain has fallen for many years.
How would the organisms in the grassland ecosystem be affected
by the drought?
There would be fewer shrubs
and there would be more deer.
There would be fewer numbers of
each type of organism.
There would be more numbers of
each type of organisms.
There would be fewer hawks and
there would be more mice.
Look at the picture of the forest.
What prevents the small trees in the forest from growing larger?
Less rain reaches the smaller trees.
Less sunlight reaches the smaller trees.
Less soil reaches the smaller trees.
Less rain, sunlight and soil reaches the smaller trees.
Rain forests normally receive a lot of rain. Which of the following is MOST LIKELY to happen to the plants in a rain forest during a severe drought and which organism might this affect?
The plants will wilt and may die. Herbivores may have less food.
The plants will quickly adapt. Herbivores may have more food.
The plants will grow taller. Carnivores
may have more food.
The plants will sprout new leaves. Carnivores may have more food.
Look at the desert food web.
What organism will possibly die out if the feather grass were removed from the desert?
Jackrabbit
Grasshopper
Desert tortoise
Desert fox
Look at the table.
Based on the Properties of Aquatic Organisms table, which organism is a producer?
Grass Shrimp
Phytoplankton
Water Snail
Zooplankton
The table lists some characteristics of producers and consumers.
Which example would best replace the “X” in the table?
Plants
Trees
Shrubs
Goats
The illustration demonstrates the relationship between plants, their environment, and the Sun. The plant uses the energy from the sunlight to produce glucose from carbon dioxide and water, while oxygen is also produced and released.
What is the purpose of this process?
Producers making their own food
Consumers making their own food
Producers consuming carnivores
Producers consuming herbivores
The food web shows interactions in a forest environment.
What statement about the interactions within the forest is correct?
Carpenter ants are producers.
Lichen are not producers.
Voles do not get energy from owls.
Black-tailed deers will not get energy from berries.
The leaves of most plants make food, using the Sun's energy, for the plant to grow. But leaves can cause a plant to lose water. This can cause the leaves to wilt, and the plant could die. Which of the following plants has leaves that are BEST adapted to prevent water loss in hot, dry climates?
A grassland food web is shown.
How many organisms obtain their energy only from producers?
