- ADecomposers
- BConsumers
- CSunlight
- DOxygen
- EProducers
Q4:
Fill in the blanks: Animals like cows feed on , and animals like tigers feed on that previously fed on producers, while feeds on dead plants and animals. Therefore, all consumers and decomposers depend on producers to get their either directly or indirectly.
