What is the term used to describe the transfer of energy from one organism to another in a food web?
energy transfer
biomass transfer
nutrient transfer
trophic level
What are the different trophic levels in a food web?
producers, primary consumers, secondary consumers, and tertiary consumers
plants, herbivores, carnivores, omnivores
predators, prey, scavengers, decomposers
autotrophs, heterotrophs, detritivores, saprophytes
What is the main difference between a food chain and a food web?
A food chain involves only one organism at each trophic level, while a food web involves multiple organisms at each trophic level.
A food chain represents a single pathway of energy flow, while a food web represents multiple pathways of energy flow.
A food web is a linear sequence of organisms, while a food chain is a complex network of interconnected food chains.
The main difference between a food chain and a food web is the complexity and interconnectedness of the organisms involved.

sunlight
rocks
wind

What is the primary source of energy in most food webs?

What happens to the amount of energy as you move up the trophic levels in a food web?
The amount of energy fluctuates.
The amount of energy stays the same.
The amount of energy decreases.
The amount of energy increases.
What is the purpose of a food web in an ecosystem?
The purpose of a food web in an ecosystem is to illustrate the feeding relationships and energy flow between different organisms.
The purpose of a food web in an ecosystem is to control the climate and weather patterns.
The purpose of a food web in an ecosystem is to determine the population size of each organism.
