According to this food chain, which organism gets the most energy directly from the Sun?
Grass
A cactus in the desert suddenly starts growing twice as fast as normal. What could be a reason?
A) Less sunlight, therefore increased photosynthesis
B) Freezing temperatire, therefore hibernation
C) Increased rainfall, therefore more water
C) Increased rainfall, therefore more water

Why does energy decrease as you move up each trophic level?
A) Because energy is lost as heat and through life processes (movement, digestion)
B) Because energy is gained through life processes (movement, digestion)
C) Because more consumers exist
A) Because energy is lost as heat and through life processes (movement, digestion)

Which trophic level normally contains the greatest number of organisms?
A) Producers, because they support all the levels above them.
B) Primary Consumers, because they support all the levels above them
C) Apex Predators, because they obtain energy from all the levels below them
A) Producers, because they receive the most energy and support all the levels above them.

C. Both abiotic and biotic factors
D. Neither abiotic nor biotic factors
C. Both abiotic and biotic factors
Your class fish tank becomes cloudy and smelly overnight. Which pair of factors could explain this change?
A) An evolutionary change causes the amount of energy lost as heat/waste between each trophic level to drop
B) A higher caloric content causes the amount of energy in metabolism to increase between each trophic level
A) An evolutionary change causes the amount of energy lost as heat/waste between each trophic level to drop
