A food web representing a Gulf Coast ecosystem is shown.
Based on this food web, what would happen if the bobcat went extinct?
In a coastal ecosystem, sea otters prey on sea urchins, which consume kelp. After sea otter populations decline due to hunting, scientists notice that kelp forests begin to disappear.
Which of the following is the most likely outcome if sea otters are permanently removed?
The diagram shows molecules that a mitochondrion uses and produces during a cellular process.
The diagram represents a cellular process.
What are the products of this reaction?
Which graphic organizer best compares the energy inputs and outputs of cellular respiration?
Which graphic organizer best compares the energy inputs and outputs of photosynthesis?
Complete the sentence by selecting the correct answers from the drop-down menus.
energy is needed for photosynthesis and energy/glucose is needed for cellular respiration.
Global warming has changed weather patterns. This affects organism that migrate, as they begin lose the innate ability to sense when they need to move. Animals that migrate includes butterflies and grouses.
Based on this food web, how would a significant decrease in the grouse population due to global warming most likely affect this ecosystem?
A food web is shown.
Identify and explain ONE effect that removal of rabbits would have on this food web.
Below there is a food web shown.
Which of the following best illustrates the flow energy through the trophic levels of the forest ecosystem in this diagram?
Krill is a small shrimp-like crustacean found throughout the world's oceans. It is considered the basis for most ocean ecosystem, and it is very sensitive to temperature change. As the world warms up, our oceans heat up as well, this affects krill reproduction, and their numbers have drastically decreased in the last few decades.
According to the food web, which of the following will most likely occur if global warming continues to affect the krill population?
The picture below shows the energy flow through a forest community.
Which statement best describes what will happen if the population of herbivores in the community decreases.
In some farmland, a symbiotic relationship exists between cows and cattle egrets. As the cow walks through the field, they stir up the insects in the field, causing the insects to fly up. The cattle egret stays near the cow, in order to consume the insects. The cattle egret does not harm or benefit the cow by eating these insects.
What is the correct classification of this symbiotic relationship?
Hippos interact with oxpeckers, ticks, and crocodiles. Ticks suck the blood from the Hippos. Oxpeckers live on the backs of Hippos and feed on the Ticks found on the Hippos skin. Crocodiles are carnivores that prey on hippos living in the same environment.
Which list describes the types of relationships the Hippo has with the other organisms?
The aphid is a small, soft-bodied insects that suck sap from plants. By sucking the sap, they take the plants nutrients, this leads to the leaves becoming damaged, curled, and turning to a brown color. Ladybugs eat aphids, and help heal these plants.
Which answer correctly identifies a relationship between two of these organisms?
The diagrams show a partial food web containing the Tachinid flies and the life cycle of the wasp.
Based on the two diagrams, which list correctly identifies the relationship that the tachinid flies have with the other two organisms?
The wolverine is a land-dwelling carnivorous predator that lives in the Northern boreal forest where they feed on voles, squirrels, and snowshoe hares. How would the removal of the wolverine impact the ecosystem of the Northern boreal forest?
The Japanese Knotweed is a low growing shrub that is native to eastern asia, and was introduced to the United States as a horticultural plant in the 19th century. It grows quickly in wide range of habitats, covering whole hills and growing over native plants, taking over most of the natural sunlight that reaches those areas.
Which statement BEST describes how the Japanese Knotweed affects the American ecosystem?
In Washington state, there is a volcano called Mount Saint Helens. In the 1980's there was a large volcanic eruption. For days afterward the sky was covered with soot and dust blocking out the sun. This lead to the smaller vegetation (plants) drying up. Which description best explains how this would affect this ecosystem?
Trophy hunting is causing a decline in animal populations in the Savannah, such as the Rhino. Rhino are being hunted faster than they can reproduce.
Which statement describes the most likely effect that trophy hunting will have on this ecosystem?
Running bamboo is an invasive plant from south east Asia, it out competes other plants and quickly take over lands and gardens. An avid gardener has had their garden overtaken by running bamboo, they have discovered an insect that eats running bamboo. They buy a large amount of this bug and release them into their garden.
How might the gardener's actions most likely have a negative impact on the ecosystem?
Climate change (Global Warming), is primarily a problem of having too much carbon dioxide in the atmosphere. Burning coal, gasoline, and oil releases carbon dioxide (CO2) into the atmosphere.
Which process removes carbon dioxide (CO2) from the atmosphere?
Based on the diagram of the forest ecosystem, which statement is true?
Which evidence supports the answer from the previous question?
