In a terrestrial ecosystem, who are the primary producers? |
Insects and birds Herbaceous and woody plants Phytoplankton and algae None of these |

The correct answer is Option (2) – Herbaceous and woody plants Primary producers are organisms that produce their own food through the process of photosynthesis, converting solar energy into chemical energy. In terrestrial ecosystems, the main primary producers are herbaceous (non-woody) plants and woody plants (trees and shrubs). These plants capture sunlight and use it to convert carbon dioxide and water into glucose and oxygen, forming the base of the food chain and supporting all other trophic levels in the ecosystem. In contrast, the other options are not primary producers in a terrestrial ecosystem:
