If the bear population decreased in the ecosystem shown to the left, what would happen to the fish population?
increase because more fish would survive and reproduce since it's a natural predator has decreased
population would decrease because the fish depend on the bear population for food.
the fish population would not be affected because the fish would get disease and some fish would die.

Consider this food web. It is rich with animal species that fill a variety of niches within the ecosystem. Imagine that a local farmer has sprayed the area with insecticide. Predict how this might impact the food web and the roles each organism plays within it.
The food web would collapse without this niche being filled.
Although the farmer's spray would wipe out the insects, the other herbivores, rabbits, squirrels, mice and birds, would take over the empty niches and the food web would continue with very little change.
One section of the food web would be greatly impacted: the section containing the insects and insect-eating animals. Without insects and possibly spiders, there would be no food for the toads and insectivorous birds.
One section of the food web would be greatly impacted: the section contains the insects and insect-eating animals. Without insects and possibly spiders, there would be no food for the toads and birds including the hawks and owls.

The freshwater mussel is found in Georgia's diverse water of the Flint River. The mussel improves the water quality by filtering out bacteria, algae and pollutants, but in doing so they accumulate contaminants in their bodies. The mussel is considered an ? as it improves the health of the river.
indicator species
endangered species
invasive species
endemic species
Why would a ecosystem that had a high species diversity be more productive and effective?
different species can complement each other in an ecosystem making it more productive
the higher the diversity, the higher the populations of all the photosynthetic organisms
animals do not need plant species so the plants are able to be more productive without the animals interactions
animals form the base of any food chain which allows many different species of plants to survive and be more productive
Tegus are not native to our state and have recently been spotted in Toombs and Tattnall counties. Tegus have been known to eat native species including the eggs of alligators and threatened wildlife, such as hatchling gopher tortoises. Tegus may be more cold tolerant than other reptile species and more likely to spread throughout the state. There are also concerns these reptiles could cause bacterial contamination of crops and spread exotic parasites to native wildlife. The Georgia DNR has classified the Tegus as a(n) ?.
keystone species
invasive species
indicator species
endangered species

An ecological pyramid is sometimes used to show both the flow of matter and energy in an ecosystem. The pyramid narrows as matter and energy flow from the bottom to the top. Draw a conclusion about what this pyramid tells you about the energy in this ecosystem.
Energy stays the same. Only the number of living things change.
Energy decreases from the top to the bottom as organisms are larger in size.
Energy increases from bottom to top because the organisms get larger in size.
Energy decreases from bottom to top because some is used at each level for life processes.
The model below demonstrates the processes of the water cycle. Water uptake to the atmosphere occurs through the processes of evaporation and transpiration from plants where it condenses to form clouds. Clouds release the water through precipitation. During a summer of extreme drought, what can we expect to happen to the surface ground water stored in ponds and lakes?
water levels will increase because there is more precipitation
animals won't drink as much to save water, so water levels remain the same
water levels will increase because there is more evaporation and transpiration
water levels will decrease because there is more evaporation and transpiration
Make a claim about the adaptations shown using your knowledge of the abiotic and biotic factors in a specific Biome. Grasslands 𝑨𝒅𝒂𝒑𝒕𝒂𝒕𝒊𝒐𝒏𝒔: 𝑭𝒍𝒂𝒕 𝒕𝒆𝒆𝒕𝒉 𝒂𝒏𝒅 𝑹𝒖𝒏 𝑭𝒂𝒔𝒕
In grasslands the temperature is generally high so animals must run fast to create wind that will keep them cool.
In grasslands the plant life is usually short so animals must run fast because there is no place to hid from predators.
In grasslands the plant life is usually high so animals must run fast to jump the tall trees an escape the predator.
Excess nitrogen can harm water bodies: Excess nitrogen can cause over stimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters. A student finds a local pond which has low turbidity water, few lily pads and small amounts of algae. What claim can the student make about the water quality?
Since there are some plant life caused by normal amounts of nitrogen, the water quality is good..
Since there is an abundance of plant life like algae caused by excess nitrogen, the water quality is bad.
Since there an abundance of plant life caused by large amount of sunlight, the water quality is good.
Since the amount of nitrogen should be at an excess level, the water quality is bad.
Organisms in the APHOTIC ZONE must be able to live in complete darkness and in close to freezing water. In the APHOTIC ZONE , there is virtually no light from the sun (1% or less of sunlight reached this zone), so photosynthesis can not take place. Consequently there are no plants or other photosynthetic organisms in this zone. 𝙒𝙝𝙖𝙩 𝙞𝙨 𝙖𝙣 𝙖𝙙𝙖𝙥𝙩𝙖𝙩𝙞𝙤𝙣 𝙩𝙝𝙖𝙩 𝙖𝙣 𝙤𝙧𝙜𝙖𝙣𝙞𝙨𝙢 𝙢𝙞𝙜𝙝𝙩 𝙝𝙖𝙫𝙚 𝙞𝙣 𝙩𝙝𝙞𝙨 𝙯𝙤𝙣𝙚?
An organism might adapt to using half of the light needed by the sun to undergo cellular respiration.
An organism might use a process called chemosynthesis, because photosynthesis does not work in this area.
The organism will not adapt because no light is available to make a change.
The organism use the process of cellular respiration to make their own food instead of consuming other organism..

Which claim could be made about using fossil fuels?
Because the amount of reserves for coal will only last about 150 years, the usage of coal to produce electricity should decrease
Because the amount of reserves for coal will only last about 150 year, the usage can continue because it releases the least amount of pollution into the environment.
Because the amount of reserves for oil will only last about 50 years, the usage for oil to create electricity should decrease.
Because the amount of reserves for all fossil fuels is less than 200 yrs, and all fossil fuels have some serious environmental issues like waste water runoff, black lung disease, and contamination during a spill. We should look to other methods of producing energy that last longer and create less environmental issues.
