The bulk fixation of carbon through photosynthesis takes place in:
Show Hint
- Crop plant and tropical rain forest
- Tropical rain forest
- Crop plants
- Oceans
The Correct Option is C
Solution and Explanation
Crop plants contribute significantly to carbon fixation, especially in managed agricultural ecosystems.
Tropical rain forests are important but contribute less compared to oceanic phytoplankton globally.
Oceans (especially phytoplankton) contribute about 50% of global carbon fixation.
The options mix terrestrial and aquatic sources; crop plants have major localized carbon fixation roles.

- The table below describes the number of tree species in a forest whose seeds are dispersed by large or small animals, and whether they are insect or wind pollinated. In the past, seed dispersers and pollinators were abundant in this forest. Now, there are very few large animal dispersers, but the number of small animal dispersers has not changed. There are also very few insect pollinators in this forest. Which one or more of the following inferences about trees in the forest can be drawn from these changes in seed dispersers and pollinators?
