Question

food webs
producers are organisms that make their food using sunlight. consumers eat to get food. humans are consumers. decomposers obtain energy by breaking down dead plants and animals.
the table below describes the energy sources for four unknown organisms.

organism	energy source
x	berries and seeds
y	rabbits, mice, and squirrels
z	sun

part a
which of the following is true about an organism’s role in the ecosystem?
a. organism x is a consumer.
b. organism y is a producer.
c. organism z is a consumer
d. organism x is a decomposer.
part b
which of the following could correctly identify an organism from the table?
a. organism w is a fox.
b. organism y is a caterpillar.
c. organism z is a tree.
d. organism x is bacteria.

Explanation:

Part A

• Producers make food using sunlight (like plants). Consumers eat to get food. Decomposers break down dead organisms.
• Organism \(Z\) uses the sun (producers use sunlight), organism \(X\) eats berries and seeds (so it's a consumer), organism \(Y\) eats animals (consumer), organism \(W\) breaks down dead tree (decomposer).

• Foxes are consumers (eat other animals/ plants), caterpillars are consumers (eat leaves etc.), trees are producers (use sun), bacteria can be decomposers.
• Organism \(Z\) uses sun (producers like trees use sun). Organism \(W\) is a decomposer (not a fox - fox is consumer), organism \(Y\) is a consumer (not caterpillar as caterpillar eats plants mainly here \(Y\) eats animals), organism \(X\) is a consumer (not bacteria - bacteria is decomposer).

Answer:

A. Organism \(X\) is a consumer.

Part B
