Answer: Option C.
Energy flows in one direction in ecosystem.
Explanation:
In the ecosystem, energy flow in one direction. Energy is transfered from one trophic level to another.
Energy is transfered from producers, majorly plants,convert sunlight to chemical energy during photosynthesis and transfer it to herbivores( goat, sheep ) when they eat plants,the herbivores after using the energy transfer energy to the carnivores when the carnivores feed on the herbivores and to decomposer who feed on dead animals.
We should care because extinction of some species will eventually create a big imbalance in the ecosystem.
For instance, man depends on plants for food and in turn plants depend on insects such as butterfly for pollination. If the pollinating insects are wipe out, the plants we be affected and if the plants are affected human will eventually be affected.
