Question

1. look at the food chain below.

dead leaves ? fungus ? beetle ? frog
what role does the fungus play in this food chain?
a. carnivore
b. consumer
c. decomposer
d. producer

1. what behavior do omnivores and carnivores share that make them consumers within a

food web?
a. they both grow.
b. they both hunt prey.
c. they both produce waste.
d. they both eat other organisms.

1. what is one thing producers do that no other contributor to a food web can do?

a. they create all the energy on earth.
b. they recycle energy in the ecosystem.
c. they convert sunlight into chemical energy.
d. they transfer energy between trophic levels.

1. in an aquatic food chain, energy is passed from the bottom level to the top. the

bottom level contains algae, which is eaten by some fish and tadpoles. the fish
are then eaten by alligators, which are at the top of the food chain. what is the
role of the algae in this aquatic food chain?
a. consumer
b. predator
c. prey
d. producer

Explanation:

1. Fungi break down dead organic matter (dead leaves here), so they are decomposers. Carnivores eat meat, consumers eat other organisms (not dead matter directly), and producers make their own food (like plants via photosynthesis).
2. Omnivores (eat plants and animals) and carnivores (eat animals) both eat other organisms. Growing is a general life - process (not specific to consumers), not all consumers hunt prey (e.g., some herbivores just graze), and producing waste is not the defining consumer behavior.
3. Producers (like plants, some algae) convert sunlight into chemical energy via photosynthesis. They don't create all energy (sun is the major energy source), decomposers recycle energy in a way (by breaking down matter), and energy transfer between trophic levels is done by all levels (consumers also transfer energy when they are eaten).
4. Algae, like plants, can perform photosynthesis. In a food chain, the role of making their own food (and being the start of the energy flow) classifies them as producers. Consumers eat other organisms, predators hunt prey, and prey are eaten (but algae's primary role is production).

Answer:

1. C. decomposer
2. D. They both eat other organisms.
3. C. They convert sunlight into chemical energy.
4. D. producer
