SCIENCE 1
The continues movement of carbon atoms between the Earth's atmosphere, ocean, living organisms, and soil.
The Carbon Cycle
A decomposer is any organism that breaks down or eats decaying material for its energy source
Decomposers
Why do plants need light?
All plants require light for photosynthesis.
Why don't plants die when they cannot make food?
Plants need to synthesize their own food because unlike other living organisms, plants
Germination is the proves by which a plant grows from a seed into a seedling.
Seed germination
A growing medium can be defined as a substance through which roots grow and extract water and nutrients.
Growing media.
The amount of fertilizer is the independent variable and the plant height is the dependent variable
Independent vs dependent variable.
To have control is to have the power to run something in an orderly way.
Control
The movement and transformation of chemical elements and the compounds between living organisms, the atmosphere, and the Earth's crust.
Matter Cycling
The process by which plants, algae, and certain bacteria use sunlight, water, carbon dioxide to create oxygen and sugar "chemical energy" as food.
Respiration
A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Respiration
Air is primarily composed of nitrogen and oxygen
The composition of air
The primary food molecule produced by plants is glucose, a simple sugar that serves as a source of energy for growth and development.
Food Molecules
Why use hydroponics?
Hydroponics is the practice of growing plants in a nutrient rich water solution instead of soil.
What is the main "ingredient" used in the process of photosynthesis?
Sunlight
