Who are the only organisms that directly use the Sun's energy?
What is producers.
100
What is the waste product of cell respiration?
What is carbon dioxide.
100
What happens first?
What is water evaporates
100
in the first step, nitrogen gas is ____.
What is converted to a useable form and returned to the atmosphere.
100
What is photosynthesis/what is used during this process?
What is when plants make food from water and carbon-dioxide. Oxygen is the waste product.
200
Who has more energy, higher level consumers or lower level consumers?
What is lower level consumers.
200
After plants use oxygen to break down their food during cell respiration, what happens?
What is they release CO2 which plants then use for photosynthesis.
200
Where is much of Earth's water?
What is glaciers, salt water, and in the soil.
200
In the second step, how is lightening used?
What is it converts nitrogen gas into nitrogen compounds and then rain carries the nitrogen compounds into the soil.
200
What is the difference between a food chain and a food web?
What is a food chain is the path that food is cycled through an ecosystem from a producer to consumers and decomposers. A food web is when food chains overlap, therefore, the consumers eat consumers from other food chains.
300
There are mice, fungi, grasshoppers, hawks, and shrubs. Name the producer, and each ORDERED consumer.
What is producer = shrubs,
grasshoppers = 1st order consumer
mice = 2nd order consumer
hawk = 3rd order consumer
fungi = 4th order consumer
300
How is the soil used in the CO2-oxygen cycle?
What is some plants get water from the soil and CO2 from the soil to start the process of photosynthesis.
300
How come the balance of water is always the same on Earth?
What is the water is constantly being recycled through Earth.
300
What happens in the third step?
What is bacteria in the soil along with the roots of plants use the nitrogen for food.
300
What are proteins?
What is the building blocks of all living things
400
What does it mean to be high, or low, on the food chain? Explain.
What is the lower you are in the food chain, the more energy you get from the foods you eat. Producers are low on the food chain. IF you are higher in the food chain, you are a higher level consumer i.e. 3rd order consumer, 4th order consumer etc.
400
List the 5 steps of the CO2 oxygen cycle.
What is cell respiration when animals eat plants, this releases CO2
Plants use CO2 for photosynthesis
Consumers eat the producers and store some energy
Animals die and decomposers break down their remains
400
Explain how condensation forms.
What is when water vapor changes from hot to cold and changes back into a liquid. I.e. your frozen water bottle on a hot day.
400
What do the plants do in step 4?
What is the use the nitrogen to make food and produce proteins.
400
What is the difference between cell respiration and transpiration?
What is cell respiration is when oxygen is used to break down carbon compounds and release energy, while transpiration is when plants release water vapor from their leaves.
500
Does the size of higher level consumers increase or decrease? Explain.
What is they decrease. This is caused by the amount of food available for them to eat. For example, a population size can only be supported by the amount of food available for them to eat. If there is to large of a population size, then the population they are eating, would become extinct.
500
Describe what cell respiration is and give an example.
What is when oxygen mixed with carbon compounds to break down the remains of plants and animals to release CO2 back to the air. When animals die they have no oxygen in them, just carbon. That carbon mixes with oxygen to release the carbon compounds and CO2
500
How are marshes used to filter water?
What is the water starts in a holding tank, is moved to a tub where the water is mixed with compounds the remove solids and break down any compounds with the help of small organisms. Decomposers can break down microscopic organisms or harmful bacteria.
500
What do the decomposers do in the final step?
What is they break down the dead remains of animals. Then the plants use the nitrogen for food and release the wasteful nitrogen back into the atmosphere so it can cycle through again.
500
There are three terms used to describe water in the water cycle at different stages. What are they and in what order do they go in?
What is first the water EVAPORATES, it is changed into a gas in the form of WATER VAPOR, then when the water vapor collects in the clouds, it gathers back together changing into a liquid in the form of PRECIPITATION.
