Minerals are elements, such as:

​Molecular Structure of Vitamins

​Each vertex represents a carbon atom.

You know all about water.

​Biogeochemical Cycles (nutrient cycles): how chemical elements move through the atmosphere, soil, rocks, bodies of water, ice, and organisms.

​Example:

​Biogeochemical Cycles (nutrient cycles): how chemical elements move through the atmosphere, soil, rocks, bodies of water, ice, and organisms.

​Example: The Nitrogen Cycle

​Biogeochemical Cycles (nutrient cycles): how chemical elements move through the atmosphere, soil, rocks, bodies of water, ice, and organisms.

​Example:

​Primary Producers: Organisms that convert carbon and water into carbohydrates and oxygen using light energy or chemical energy.

Multiple Choice

Which of the following is a producer?

​Photosynthesis: The process by which green plants and some other organisms use light energy to make carbohydrates and oxygen gas from water and carbon dioxide.

Multiple Choice

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the stem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

Multiple Select

Select all that are products of Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Carbohydrates)

​Consumers: Organisms, mainly animals, that must eat other organisms to get energy.

​Decomposers: Organisms such as bacteria and fungi that break down wastes and dead organisms to obtain energy and release nutrients, like carbon and nitrogen, into the soil and water.

Multiple Choice

A mushroom is a 

• producer
• consumer
• decomposer

Multiple Choice

A carrot is an example of a 

• producer
• consumer
• decomposer

Multiple Choice

A cougar is a 

• producer
• consumer
• decompser

​Cellular Respiration: The process by which organisms use oxygen to break apart glucose (sugar) to release energy. This also produces carbon dioxide (CO₂) and water.

​Mitochondria:

​Be careful:
ALL organisms do SOME type of cellular respiration!
EVEN PRODUCERS. Plants need energy too.
