Explanations: answer key for all 10 questions
- Q1: What usually begins a food chain?
Answer: A producer like a plant
Producers make food from sunlight.
- Q2: What is an animal that eats plants called?
Answer: Herbivore or primary consumer
Rabbits and deer are herbivores.
- Q3: What is an apex predator?
Answer: A predator at the top with no natural enemies
Orcas and lions are apex predators.
- Q4: About what fraction of energy passes from one level to the next?
Answer: About 10%
Most energy is used or lost as heat.
- Q5: What is a food web?
Answer: Many connected food chains
Most animals eat more than one thing.
- Q6: Which organisms return nutrients to the soil?
Answer: Decomposers like fungi and bacteria
They break down dead matter.
- Q7: What is an animal that eats both plants and animals?
Answer: Omnivore
Bears and humans are omnivores.
- Q8: What forms the base of most ocean food chains?
Answer: Phytoplankton
Tiny algae feed zooplankton.
- Q9: Why are there fewer top predators than herbivores?
Answer: Less energy reaches higher levels
Energy pyramids narrow at the top.
- Q10: What is biomagnification?
Answer: Toxins building up at higher food chain levels
DDT harmed eagles this way.
Food Chains Quiz – Who Eats Whom
Food chains show how energy moves from one living thing to another. They start with producers, usually plants or algae, which capture sunlight. Herbivores eat producers, carnivores eat herbivores and decomposers break down dead matter.
In real ecosystems, food chains connect into food webs, since most animals eat many things. Only about 10% of energy passes to each level, which is why there are far fewer top predators than plants or herbivores.
Changes in one part of a food web can ripple through the whole system. Removing predators, adding invasive species or polluting water can upset balances, while protecting key species can restore ecosystems.
