Study Island pretest
Consumers eat producers and decomposers get nutrients from both when they die.
What do you mean by consumers?A food chain consumer is an organism that eats organisms from different populations. The consumer is a heterotroph and the producer is an autotroph.
Organisms that eat producers are primary consumers. They are usually small and numerous. The main consumers are herbivores (vegetarians).
Consumers play an important role in the ecosystem by regulating the population growth of organisms and supplying energy to other organisms. Removing any species, producer or consumer from an ecosystem can destabilize the ecosystem.

Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long, narrow tail that originates in the mantle. This type of volcanism, hot spot volcanism, is unique. Why?
A The hot spot volcanoes rarely result in mountain building; they are a destructive process.The hot spot volcanoes rarely result in mountain building; they are a destructive process.

Mount Everest is the world's highest mountain. It is 29,028 feet (9km) above sea level. It is located in the Himalayas between Nepal and China. But now that we have sonar, we know about Mauna Kea. Mauna Kea is on Hawaii Island. It is 13,448 feet (4km) above sea level. From its base on the ocean floor, it is 33,796 feet (10km)! Should we still consider Mount Everest to be the highest mountain? Why or why not?
Answer:
I think Mount Everest should still be called the highest mountain
Explanation: Based on tradition, mountains are not measured from their bases but from sea level so considering this Mount Everest should still be called the highest mountain in the world. However despite this, some may say it should not be.

List the 3 names of the 3 inputs of photosynthesis using the chemical formulas
6CO2 + 6H2O → C6H12O6 + 6O2
Explanation:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
