What is hydroponics?

Hydroponics is a process with out soil.

100
How much did the seed weigh in the begin of the project?

Most of the seeds we started with had a mass of about 0.25 grams.

100

What is the role of a decomposer?

Decomposers RECYCLE energy from the soil.

100

What do the food chain and food webs BOTH show?

Food webs AND chains both shows the flow of energy

100

What is a water cycle?

The cycle of water.

200

What does hydro mean?

It means water.

200

What happened in the end of the project?

The mass of ONE plant, after 7 days, was between 2-4 grams.

200

What do decomposers do?

Decomposers breakdown dead organisms and energy in them to the sun.

200

They both also show which organism consume ________________. 

They both also show which organism consume which organism.

200

What is a nitrogen cycle?

The cycle of nitrogen. 

300

Why is hydroponics better than a plant with soil?

Because the ground it takes longer to get the water.

300

What do plants need to make for respiration & photosynthesis.

Plants used water, CO2, oxygen and sunlight for respiration & photosynthesis.

300

What is the balance of the decomposers in ecosystem?

Decomposers are responsible for the BALANCE of energy in an ecosystem.

300

What flow do both food chain and food web show?

They both show the direction of the flow of energy.

300

What is the carbon/fossil fuel cycle?

A cycle coating carbon. 

400

What do hydroponics do?

The same thing that photosyhts but with out soil.

400

How is the process photosynthesis made?

The carbon dioxide from the air, through photosynthesis, is the source of all matter needed to change a small seedling into a huge tree. The energy for life is derived from the sun.

400

What is the scientific word for spcaltiy? 

Niche.

400

How many flows do food chains show?

Food chains only SHOW ONE DIRECTION OF THE FLOW.

400

What does the carbon/oxygen cycle show?

Carbon/oxygen.

500

Hydroponics is a process with out soil.

What is hydroponics?

500

In other words-The mass of a plant is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

What is plants mass made of?

500

What is a niche?

500

In contrast, food webs show multiple directions of energy flow.

How many flows does a food web have?

500

They keep going and going.

What do all of these cycles have in common?
