• ecology
• ecosystem

Non-living factor that affects an ecosystem

• biotic factor

• biome

What is the original source of almost all energy in most ecosystems?

• carbohydrates
• sunlight
• water
• carbon

The difference between weather and climate is that climate is:

• The average, year-to-year conditions

• The day-to-day conditions

• Described in terms of months at a time

• It describes the atmosphere’s composition.

In this photo, what is an abiotic factor?

• Deer

• Grass

• Native Species

What percentage of energy is passed on to the next trophic level?

• 5%

• 10%

• 50%

• 90%

Green plants are

• producers
• consumers
• herbivores
• omnivores

What does a food web represent?

• All connections of energy flow throughout all organisms in a habitat.
• The specific ways that mutualism is carried out.
• A single pathway or energy flow between organisms. 
• How carnivores get their food.
