photosynthesis is the base of all food webs
primary consumers would have nothing to eat
all of the above

Answer 1

The correct answer is all of the above.

1. Photosynthesis makes oxygen that animals can breathe: During the process of photosynthesis, plants convert carbon dioxide and water into glucose and oxygen, which is essential for most living organisms that rely on oxygen for respiration.

2. Photosynthesis is the base of all food webs: Photosynthesis is fundamental to the energy supply of ecosystems. Plants (and some other organisms) produce organic compounds that serve as food for primary consumers, forming the foundation of food webs.

3. Primary consumers would have nothing to eat: Without photosynthesis, there would be no plants to provide food for primary consumers (herbivores), which would disrupt the entire food chain.

Thus, photosynthesis plays a crucial role in supporting life on Earth by producing oxygen and serving as the foundation of food chains.
