How would a reduction in the snail population affect this ecosystem?
It would cause decreased competition between spiders and owls.
It would cause increased competition between grasshoppers and beetles.
It would cause increased competition between wood mice and shrews.
It would cause decreased competition between spiders and wood mice.
Read the passage about the West African black rhinoceros. The West African black rhinoceros became extinct in 2011. Before they became extinct, these rhinos could be found across central and western Africa. They had gray skin and pointy lips, and they ate many kinds of plants. They took shelter from the Sun during the day, and they ate in the evening. For protection from the Sun and insects, they found watering holes and rolled in mud. People used their horns for medicine and decoration.
Which is the most likely reason the West African black rhinoceros became extinct?
They could no longer find food.
Their habitats were destroyed.
They were hunted by humans for their horns.
The watering holes where they got mud dried up.

The picture shows a food web in the mountains of Georgia.
The sun is at the top of the food web.
The bear is a primary producer.
The rabbit is a consumer.
The mushrooms are producers.
Which best describes a food web?
a less complex food chain that shows how producers gain their energy from the Sun
a more complex food chain that shows how organisms are able to digest their nutrients
a combination of food chains that show how organisms interact to get their required energy and matter
a single food chain that shows how organisms interact to get their required energy and matter
Which type of organisms are found at the base of an energy pyramid?
Carnivores
Producers
Herbivores
Scavengers
Which best describes the organisms that would recycle decaying matter back into the mountain ecosystem?
The mushrooms because they are decomposers and break down matter to return to the ecosystem.
The Sun because it provides all the energy required for the organisms to return matter to the ecosystem.
The deer because they are consumers and break down the matter from producers to return to the ecosystem.
The berries and flowers because they are producers and are broken down for multiple consumers in the ecosystem.

Which scenario would lead to the biggest increase in a rabbit population?
increase in food supply and decrease in predators
increase in food supply and predators
decrease in food supply and increase in predators
decrease in food supply and predators
In the early 1900s, the Florida panther was found all over Florida. By 1967, the population had dropped to only 30 panthers statewide, and the panther was listed as an endangered species. What is the most likely reason for the decline in the panther population?
Florida's climate changed dramatically
Panthers were hunted by humans for many years
The panthers moved north into Georgia and South Carolina
Alligators stopped eating other animals and started eating panthers
In parts of the northwestern United States, logging is destroying many of the forests that are home to the spotted owl.

there is a parasitic relationship between the organisms.
the organisms have a predator-prey relationship.
there is at least one resource that is required by both organisms.
the organisms do not harm or benefit one another.
Which type of organisms get their energy DIRECTLY FROM THE SUN? (HINT THIS NEEDS SUN TO GROW FIRST)
Producers

Primary Consumer
Secondary Consumer
Decomposition and decay of organic matter are accomplished by the action of
Scavengers

Hogs were brought to Florida by Spanish explorers in the 1500s for livestock, but some of the animals escaped and were able to survive in the wild. Florida now has a population of about 500,000 wild pigs that have descended from the Spanish stock. The feral pigs' favorite food is acorns, but they also eat agricultural crops and tree seedlings, damaging farm and forest lands. What would be the most likely outcome of an increase in the feral pig population?
A decrease in the population of squirrels
A decrease in the population of mountains lions.
An increase in farming
A
What will happen if a nonnative plant thrives in a plant community of native plants?

It became native are two growing seasons.
It will become established and take over the native plants.
It will only grow if it becomes similar to the native plants.
